Complete the labeling of plant and animal cells and fill in the blanks about cell structures and functions.

Task 1: Complete the labeling of the cells.

#### Plant Cell (Left):
1. Cell Wall: The rigid outer layer that provides structural support and protection.
2. Cell Membrane: A semi-permeable membrane that controls the movement of substances in and out of the cell.
3. Chloroplasts: Organelles containing chlorophyll, where photosynthesis occurs.
4. Vacuole: A large storage organelle that holds water, nutrients, and waste products.
5. Cytoplasm: The gel-like substance inside the cell membrane where cellular activities occur.
6. Nucleus: The control center of the cell, containing genetic material (DNA).
7. Mitochondria: Organelles responsible for producing energy through cellular respiration.
8. Endoplasmic Reticulum (ER): A network of membranes involved in protein and lipid synthesis.
9. Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for transport.
10. Ribosomes: Sites of protein synthesis, either free in the cytoplasm or attached to the ER.

#### Animal Cell (Right):
1. Cell Membrane: Controls the movement of substances in and out of the cell.
2. Nucleus: Contains genetic material (DNA) and controls cellular activities.
3. Mitochondria: Produces energy through cellular respiration.
4. Endoplasmic Reticulum (ER): Involved in protein and lipid synthesis.
5. Golgi Apparatus: Modifies, sorts, and packages proteins and lipids.
6. Lysosomes: Contain digestive enzymes for breaking down waste materials.
7. Ribosomes: Sites of protein synthesis.
8. Centrioles: Involved in cell division (mitosis).

Task 2: Complete the blank parts.

#### a)
- Nucleus: contains the genetic material called DNA, that enables the cell to perform its living functions & divide to form new cells.

#### b)
- Chloroplast: it is where the process of photosynthesis in plant cells occur. Contains chlorophyll, that is green in colour.

#### c)
- Mitochondria: are small structures where the process of respiration occurs. During respiration, energy is released from food & used for cellular activities.

#### d)
- Cytoplasm: is a jelly-like substance surrounding the organelles structures of the cell. It transports substances around the cell & it is where the cell’s waste products are broken down.

#### e)
- Cell wall: is a rigid structure on the outside of the cell. It supports the cell & gives it shape & also allows gases & fluids to pass through it.

#### f)
- Cell membrane: is the outermost structure of the cell. It allows only some substances to pass through it.

#### g)
- Vacuole: present in both plant & animal cells. It is storage space that contain water, nutrients, and waste products surrounded by a membrane.
