Flashcards in Organelle Functions Deck (14):
1

Nucleus

- Double Membrane
- communicates with surrounding cytoplasm via nuclear pores
- Holds DNA responsible for providing cell with unique characteristics

2

Nucleolus

- prominent structure in the nucleus
- produces ribosome is that leave necklace and attach to the rough endoplasmic reticulum

3

Cytoplasm

- "Soup"which organelles reside within
- Majority of cellular metabolism occurs here

4

Centriole (Centromere)

- made of microtubules which become spindle fibres, which are used to separate DNA strands

5

Golgi Apparatus

- Membrane bound structure with a single membrane
- Package macromolecules for transport elsewhere in cell

6

Cell Membrane

- Protective barrier from water for phospholipids which are hydrophobic.
- Presence of proteins crucial to cell activities, receptors for odours, tastes and hormones.
-pores to control movement of materials through cell.

7

Mitochondria

- folds within double membrane (Cristae) aware sugar is combined with oxygen to provide energy for the cell

8

Vacuole

- Membrane bound sac that plays role in intracellular digestion, release of cellular waste products.
- Larger in plant cells, regulates turgor pressure, collects water, stores nutrients

9

Cell Wall

- Rigid protective wall that provides and maintains the shape of plant cells and serves as a protective barrier.
- Fluid stored in vacuole pushes against cell wall, creating turgor pressure.

10

Chloroplast

- Contains chlorophyll, responsible for plants green colour and ability to absorb sunlight into energy through process of photosynthesis.

11

Smooth Endoplasmic Reticulum

- Network of membrane bound vesicles and tubules.
- Differing functions depending on cell type, such as lipid and steroid hormone synthesis.
E.g. breakdown of toxins in liver cell

12

Rough endoplasmic reticulum

- Appears rough due to ribosomes on its surface
- Proteins synthesised on ribosomes collect in endoplasmic reticulum for transport through cell.

13

Ribosome

- Site of protein synthesis
- messenger RNA from nucleus moves along ribosome where transfer RNA add amino acid molecules to protein chain.

14

Lysosome

- In white blood cells, lysosomes are released into the vacuole around bacteria which are then digested and killed
