Worksheet 1: Basics of Biology - Identify parts of a plant cell with multiple-choice questions.

I will solve this biology worksheet by identifying the labeled parts of the plant cell and answering the multiple-choice questions. I'll start by examining the image closely to understand the diagram and then answer each question one by one.

First, I need to identify what type of cell is shown in the diagram. Based on the presence of chloroplasts (green structures), a large central vacuole, and a cell wall, this appears to be a plant cell. I'll now go through each question systematically.

Question 1: Identify the part labeled "1".

Looking at the diagram, label "1" points to the large, clear, oval-shaped structure in the center of the cell. This is characteristic of a vacuole in plant cells, which stores water, nutrients, and waste products.

Question 2: Identify the part labeled "2".

Label "2" points to the small, green, oval-shaped structures scattered throughout the cytoplasm. These are chloroplasts, which are responsible for photosynthesis in plant cells.

Question 3: Identify the part labeled "3".

Label "3" points to the small, rod-shaped structures with internal membranes. These are mitochondria, which are the powerhouses of the cell, producing energy through cellular respiration.

Question 4: Identify the part labeled "4".

Label "4" points to the outermost layer of the cell, which provides structural support. This is the cell wall, a rigid layer found in plant cells but not in animal cells.

Question 5: Identify the part labeled "5".

Label "5" points to the large, round structure with a darker center (nucleolus). This is the nucleus, which contains the cell's genetic material and controls cellular activities.

Question 6: What is the function of a Vacuole?

The vacuole in plant cells primarily serves as a storage area for water, nutrients, and waste products. It helps maintain turgor pressure, which keeps the plant cell rigid.

Now, I will provide the final answers for each question.

Answer:
(1) (B) Vacuole
(2) (C) Chloroplast
(3) (D) Mitochondrion
(4) (A) Cell wall
(5) (B) Nucleus
(6) (C) It provides a storage area for food, water and waste.
