Parts of a cell

Question 1

Chloroplasts

Answer 1

Found in some plant cells. Contain chlorophyll in which photosynthesis takes place. It is composed of many folded layers of membrane.

Question 2

Cytoplasm

Answer 2

Found in all cells. The contents of a cell, other than the nucleus. It is more than 90% water and contains ions, salts, enzymes, food molecules and organelles.

Question 3

Endoplasmic reticulum

Answer 3

It may be rough or smooth. It is involved with the production, processing, transport and storage of materials within the cell.

Question 4

Golgi Apparatus

Answer 4

A stack of flat membrane sacs where the final synthesis and packaging of proteins occurs before they are secreted from the cell.

Question 5

Nucleus

Answer 5

A large organelle surrounded by a membrane and contains genetic material and controls cellular activities.

Question 6

Cell membrane

Answer 6

Encloses the cytoplasm in all cells. It controls the movement of substances into and out of the cell.

Question 7

Ribosomes

Answer 7

Tiny organelles located in the cytoplasm. They are sites for production of proteins.

Question 8

Vacuoles

Answer 8

Liquid filled spaces found in most cells in variable numbers. Plant cells typically have large fluid filled vacuoles containing cell sap that provided physical support and storage. In other cells, vacuoles may be involved in intracellular digestion or water balance

Question 9

Cell Wall

Answer 9

Important part of plant cells and bacteria. In plant cells it contains cellulose. It supports, prevents expansion of the cell and allows water and dissolved substances to pass freely through it.

Question 10

Mitochondria

Answer 10

Organelles composed of many folded layers of membrane involved in the energy transformations that release energy for use by the cell.
