Question 1

chloroplasts

Answer 1

Organelles found only in the plant cells, in which sugar is made during photosynthesis

Question 2

cell wall

Answer 2

A stiff outer layer that surrounds a plant cell, protect it, and gives it its shape

Question 3

nucleus

Answer 3

The control center of a cell that directs the cell’s activities

Question 4

chromosomes

2. All life processes take place in cell.
3. New cells are produced from existing cells.

Question 7

How do the parts of a cell function?

• nucleus
• cell wall
• cytoplasm
• mitochondria
• cell membrane
• vacuole
• chloroplast
• nuclear membrane

Answer 7

nucleus: it controls of the cell.

cell wall: found is in plant cells. It can protect the cell and gives it its shape

cytoplasm: it is like jelly and it is clear.

mitochondria it is like a battry for the cells.

cell membrane:it is like a bag that holds everything in the cell

vacuole: it keeps the nutrients and wastes.
chloroplast: found only plant cells, photosynthesis happens here.

nuclear membrane:it holds the nulecus.
