Organelles

Question 1

• Controls what substances enter and leave the cell
• Made of two layers of lipids
• Is known as a partially permeable membrane

Answer 1

Cell Membrane

Question 2

• Fluid content of the cell, including cell organelles, excluding the nucleus
• consists of water with dissolved sugars, salts, proteins, and oxygen

Answer 2

Cytoplasm

Question 3

-Fluid contents of a eukaryote cell excluding the organelle

Answer 3

Cystosol

Question 4

• Largest cell organelle
• Contains DNA and chromosomes
• Controls all activities in cell
• Bound by a membrane- Contains a Nucleolus which produces ribosomes

Answer 4

Nucleus

Question 5

• Consists of a system of membranes

- Directly connected to the nuclear membrane

Answer 5

Endoplasmic Reticulum

Question 6

• Surface covered in ribosomes

- Packages proteins made by ribosomes out of the cell

Answer 6

Rough Endoplasmic Reticulum

Question 7

• Free of ribosomes

- Responsible for the synthesis (making) of lipids, carbs and hormones

Answer 7

Smooth Endoplasmic Reticulum

Question 8

• Used for protein synthesis

- Either free in the cytoplasm or attached to the endoplasmic reticulum

Answer 8

Ribosomes

Question 9

• Double membrane with folded inner centre
• Convert glucose into ATP (site of cellular respiration)
• Energy centre for the cell

Answer 9

Mitochondria

Question 10

• Takes proteins from rough endoplasmic reticulum and further prepares them for distribution to the cytoplasm or out of the cell

Answer 10

Golgi Apparatus

Question 11

• Small Vesicle containing disgestive
• Intracellular digestion
• Can breakdown damaged organelles and cells

Answer 11

Lysome

Question 12

• Membrane bound sac filled with water

- Plays a role in intracellular digestion, waste release and turgor pressure (keeping the plant upright)

Answer 12

Vacuole

Question 13

• Site of photosynthesis

- Contains Chlorophyll which give plants their natural colour

Answer 13

Chloroplast

Question 14

• Composed of cellulose and shitin
• Located outside the cell membrane
• Provides structural support and prevents overexpansion when water enters the cell
• Give rigidity and strength to the cell
• Flexibility to a point

Answer 14

Cell wall

Question 15

• Filamento of protein which hold organelles in place within the cell

Answer 15

Cystoskeleton
