Diagram of a cell - plant cell diagram

Practice the diagram of a cell with this drag and drop activity. This game is specifically about a plant cell.

 

This page contains a plant cell diagram worksheet online which students can interact with. It is a diagram of a cell showing the different parts. However, at the start, these parts are scrambled. Students simply have to drag and drop the parts of the cell from a set of choices. The beauty of this exercise is that is has been made to appear like an online biology game. Students can review with this exercise at home while teachers can use it to make their biology classroom much fun. The fun does not take away the fact that students get to learn a lot during the process. Isn’t it amazing to understand that the basic structural and functional unit of life has other smaller units which play specific functions within it? Start by learning how to label and plant cell diagram through the online game and worksheet. In the end also start to find the main differences between animals and plant cells based on their structures. This exercise is for students in 1st, 2nd, 3rd, 4th, 5th, 6th and 7th grades.

Plant cell diagram parts and their functions

Plant cells are eukaryotic cells, meaning they have a true nucleus and membrane-bound organelles. The cell wall, cell membrane, cytoplasm, and organelles are the main components of a plant cell.

1. Cell wall: The cell wall is a rigid, protective layer outside the cell membrane. It is made of cellulose, a structural carbohydrate, and provides support and protection to the cell.

2. Cell membrane: The cell membrane is a thin, flexible barrier that surrounds the cell and separates the inside from the outside environment. It is made of lipids and proteins and controls the movement of substances in and out of the cell.

3. Cytoplasm: The cytoplasm is the semi-fluid substance found within the cell membrane, where all the chemical reactions of the cell take place. It contains various organelles, such as ribosomes, mitochondria, and the endoplasmic reticulum.

4. Nucleus: The nucleus is a large, spherical organelle found in the cytoplasm. It contains the cell's genetic material, called DNA, and controls the cell's activities. The nucleus is surrounded by a double membrane called the nuclear envelope.

5. Ribosomes: Ribosomes are small, granular organelles found in the cytoplasm and nucleus of the cell. They are the site of protein synthesis, where amino acids are joined together to form proteins.

6. Endoplasmic reticulum (ER): The endoplasmic reticulum is a network of flattened sacs and tubes found in the cytoplasm. There are two types of ER: smooth and rough. The smooth ER is involved in the synthesis and modification of lipids, while the rough ER is involved in protein synthesis and transport.

7. Golgi apparatus: The Golgi apparatus is a stack of flattened, membrane-bound sacs found near the nucleus. It modifies, sorts, and transports proteins and lipids to their destination within the cell or outside the cell.

8. Mitochondria: Mitochondria are small, rod-shaped organelles found in the cytoplasm. They are the site of cellular respiration, where energy is produced in the form of ATP.

9. Chloroplasts: Chloroplasts are large, green organelles found in the cells of plants and some other photosynthetic organisms. They contain pigments called chlorophyll, which absorb sunlight and convert it into chemical energy through photosynthesis.

10. Vacuoles: Vacuoles are large, fluid-filled organelles found in the cytoplasm of plant cells. They store water, enzymes, pigments, and other substances. The central vacuole in a mature plant cell can take up most of the cell's volume.

11. Peroxisomes: Peroxisomes are small, spherical organelles found in the cytoplasm of plant cells. They contain enzymes that detoxify harmful substances and remove excess hydrogen from metabolic reactions.

12. Plasmodesmata: Plasmodesmata are small channels that pass through the cell wall and cell membrane, connecting plant cells to each other. They allow for the movement of materials, such as water, sugars, and signaling molecules, between cells.

In addition to these main organelles, plant cells also contain smaller structures called inclusions, which are storage deposits of various substances, such as starch, oil, and pigments.

Questions and answers on plant cells

Here are some questions and answers about plant cells:

1. What are the parts of a plant cell?

• The parts of a plant cell include the cell wall, cell membrane, cytoplasm, nucleus, nucleolus, endoplasmic reticulum, Golgi apparatus, mitochondria, peroxisomes, vacuoles, plastids, and lysosomes.

2. What is the function of the cell wall in plant cells?

• The cell wall is a rigid, protective layer that surrounds the cell membrane of plant cells. It provides structural support and protection to the cell, and helps the plant maintain its shape.

3. What is the function of the cell membrane in plant cells?

• The cell membrane is a thin, flexible barrier that surrounds the cytoplasm of a cell and separates the inside of the cell from the external environment. It acts as a selective barrier, allowing some substances to pass through while preventing others from entering the cell.

4. What is the function of the cytoplasm in plant cells?

• The cytoplasm is the gel-like substance that fills the cell and surrounds the cell organelles. It is composed of water, salts, and organic molecules. The cytoplasm plays a number of important roles in the cell, including serving as the site of metabolic reactions, helping to maintain the shape of the cell, and allowing for the movement of organelles and other cell components.

5. What is the function of the nucleus in plant cells?

• The nucleus is the central organelle of the cell and is surrounded by a double membrane called the nuclear envelope. It contains the cell's genetic material (DNA) and controls the cell's growth and function by directing the synthesis of proteins and other important molecules.

6. What is the function of the endoplasmic reticulum in plant cells?

• The endoplasmic reticulum (ER) is a series of flattened, interconnected sacs and tubes that are found within the cytoplasm of the cell. There are two types of ER: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER). The SER is involved in the synthesis and storage of lipids, while the RER is involved in the synthesis and modification of proteins.

7. What is the function of the Golgi apparatus in plant cells?

• The Golgi apparatus, also known as the Golgi complex or Golgi body, is a stack of flattened membrane-bound sacs that is found near the nucleus of the cell. It is involved in the modification, sorting, and transportation of proteins and lipids within the cell.

8. What is the function of mitochondria in plant cells?

• Mitochondria are small, bean-shaped organelles that are found in the cytoplasm of plant cells. They are the primary site of cellular respiration, which is the process by which cells convert nutrients into energy.

9. What is the function of vacuoles in plant cells?

• Vacuoles are large, membrane-bound organelles that are found in the cytoplasm of plant cells. They are used to store various substances, such as water, salts, pigments, and enzymes. In plant cells, the central vacuole is usually the largest organelle and can make up as much as 90% of the cell's volume.
