1) found on surface of animal cells + inside cell wall of plant cells+prokaryotic cells. 2). Made of mainly lipids + proteins.
1 of 27
Function of 'Plasma (cell surface) membrane'?
1) regulates movement of substances into + out of cell 2). Has receptor molecules on it, allowing it to respond to chemicals (i.e-hormones)
2 of 27
'Cell Wall'?
1). Rigid structure that surrounds plant cells 2). Made mainly of carbohydrate cellulose
3 of 27
Function of 'cell wall'?
Supports plant cells.
4 of 27
'Nucleus'?
1). Large organelle surrounded by nuclear envelope (double membrane) contains many pores 2). Nucleus contains 'chromatin' (made of DNA + Proteins) 3) structure called 'Nucleolus'
5 of 27
Function of 'Nucleus'?
1) controls cell activity 2). DNA contains instructions to make proteins 3). Pores allow substances(i.e-RNA) to move between the nucleus + cytoplasm 3). Nucleolus makes ribosomes.
6 of 27
'Lysosome'?
1) round organelle surrounded by a membrane- no clear internal structure
7 of 27
Function of 'Lysosome'?
1) contains digestive enzymes 2). Kept separate from cytoplasm by surrounding membrane 3). used to digest invading cells or break down worn out components of the cells.
8 of 27
'Ribosomes'?
1) very small organelle 2). floats free in the cytoplasm or attached to RER 3). Made up of proteins + RNA 4) Not surrounded by membrane
9 of 27
Function of 'Ribosomes'?
Site where proteins are made.
10 of 27
'Rough Endoplasmic Reticulum (RER)'?
1) system of membranes enclosing a fluid-filled space. 2). Surface is covered with Ribosomes
11 of 27
Function of 'Rough Endoplasmic Reticulum (RER)'?
1) Folds + processes proteins that have been made at the ribosomes
12 of 27
'Smooth Endoplasmic Reticulum (SER)'?
Similar to RER but no Ribosomes
13 of 27
Function of 'Smooth Endoplasmic Reticulum (SER)'?
Synthesises + Processes lipids
14 of 27
'Vesicle'?
Small fluid-filled sac in the cytoplasm, surrounded by a membrane
15 of 27
Function of 'Vesicle'?
1) Transports substances in + out of the cell (via plasma membrane) + between organelles 2). some formed by Golgi apparatus or the endoplasmic reticulum + others formed at cell surface.
16 of 27
'Golgi Apparatus'?
1). Group of fluid-filled membrane-bound sacs 2). Vesicles are often seen at the edges of the sacs.
17 of 27
Function of 'Golgi Apparatus'?
1). processes + packages new lipids + proteins 2). Makes lysosomes
18 of 27
'Mitochondria'?
1) Oval-shaped 2). Double membrane-inner folded to form 'Cristae' 3). Inside is the matrix- containing enzymes involved in respiration
19 of 27
Function of 'Mitochondria'?
1) site of aerobic respiration -where ATP is produced 2). Found in large numbers in cells, very active + require a lot of energy.
20 of 27
'Chloroplast'?
1) small, flattened structure found in plant cells.2)surrounded by a double membrane-membranes inside='thylakoid membranes' 3).'thylakoid membranes' stacked up to form Grana4) Grana linked together by lamellae-thin, flat pieces of thylakoid membrane.
21 of 27
Function of 'Chlororplast'?
1) site where photosynthesis takes place 2) photosynthesis takes part in the grans + other parts in the storma
22 of 27
'Centriole'?
1). Small hollow cylinder made of microtubules (tiny protein cylinders) 2). found in animal cells, but only some plant cells
23 of 27
Function of 'Centriole'?
Involved with the separation of chromosomes during cell division
24 of 27
'Cilia'?
1). Small, hair-like structures found on surface membrane of some animal cells 2). Cross-section: they have an outer membrane + ring of nine pairs of protein microtubules inside, with two microtubules in the middle.
25 of 27
Function of 'Cilia'?
1) Microtubules allow cilia to move 2). Movement is used by the cell to move substance along the cell surface.
26 of 27
'Flagellum'?
Flagella on eukaryotic
