3. new cells are produced from existing cells.

Question 8

Explain how the parts of the cell function

• nucleus
• cell wall
• cytoplasm
• mitochondria
• cell memrane
• vacuole
• chloroplast
• nucleur membrane

Answer 8

nucleus: It controls all of the cell.

cell wall: It protect the plant cell and gives it shape.

cytoplasm: The organelle sits in it. It’s clear and like jelly.

mitochondria : Help make energy for the cell.

cell membrane: Is is the bag that holds the cell and they let the things go in and out.

vacuole: It cleans all of the dirty things in cell and the holds nutrients and wastes.
chloroplast: It is where photosynthesis happens.

nucleus membrane: it’s like a bag that holds everything in the nucleus
