Nucleus
1)What is the nucleolus of a cell? (knowledge)
- double layered membrane that encloses the contents of the nucleus during most of the cell’s lifecycle
- the space between the outer and inner membrane of the nuclear envelope
- the grand granular structure within the nucleus of a cell and composed of protein and RNA
d. an organelle made up of 1/3 protein and 2/3 RNA, where protein synthesis takes place
2) The nucleus is similar to… (application)
a. muscles
b. the brain of the human body
c. heart
d. fingers
3) Diagram/Outline the nuclear envelope (analysis)
4) True or False
The perinuclear space is the space between the inner and outer membrane of the nuclear envelope
True
5) What does the nuclear pore complex do?
It regulates the movement of materials across the nuclear envelope.
Power Stations
6) What is a mitochondria?(knowledge)
- series of continuous loops that loop back and forth between nucleus and plasma membrane
- tiny hair like structures
- a bond formed by amino acids
- a sausage shaped organelle which converts food into energy by breaking bonds of glycogen molecules, ATP and ADP
7)What are the part of a chloroplast?(Analysis)
8) Why is chloroplast significant? (Applicationn)
Chloroplasts are where photosynthesis takes place, making food for the cell.
9) True or False
The more mitochondria there are, the less active the cell is
False, the more mitochondria there are, the more active the cell is.
10) What are the 3 main types of plastids found in plants?
Leucoplasts, chromoplasts, chloroplasts
Cytoskeleton
11)What is a microtube? (knowledge)
- straight hollow tube of proteins that gives rigidity, shape, and organization to a cell
- a network of fibers extending through the cytoplasm
- a long tail
- a protein
12)What are the differences between cilia and flagella? (Analysis)
Cilia is a tiny hair- like structure. It covers the cell membrane, move liquids and other substances over the cell. It moves in an oar-like motion. Cilia contain bundles of microtubes. Flagella has a long-tail. There is usually one or two flagella in a cell, but there can be more. Flagella helps the cell by acting as a propeller It moves in a snake-like motion. It has a core of microtubes.
13) Why are the cell walls significant? (application)
They give the cell structure and shape.
14) True or false
The primary cell wall contains cellulose, hemicellulose, pectin, albeit in different proportions, polysaccharides, proteins.
True
15) Define cytoskeleton
Network of fibers extending through the cytoplasm
Endoplasmic Reticulum
16 )How does the rough endoplasmic reticulum use exocytosis? (Application)
It is used as a transport system to the golgi apparatus to get proteins out of the cell.
17)How can you tell the difference between the rough endoplasmic reticulum and the smooth endoplasmic reticulum? (knowledge)
a. by their width and height
b. by their color
c. the rough endoplasmic reticulum is studded with ribosomes and the smooth E.R is not
d. by their size
18) Define Cisternae.
Flat intermembrane space that makes up the golgi apparatus within the cells
19) True or false
The primary cell wall contains cellulose, hemicellulose, pectin, albeit in different proportions, polysaccharides, proteins.
True
The ribosomes on the rough endoplasmic reticulum indicates that it is involved with Protein Synthesis
True
20) Diagram/Draw a rough endoplasmic reticulum. (Anaylsis)
Peroxisomes
21)What are microbodies? (knowledge)
- DNA
- a membrane bound organelle which is present in all plants and fungal cells
- a saclike cellular organelle that contains vacuoles hydrolytic enzymes
- group of organelles that are found in the cytoplasm of most cells
22)True or false
Peroxisomes are plastids.
False, peroxisomes are microbodies
23) Why are peroxisomes significant in plants? (Application)
The peroxisomes in their seeds are responsible for the conversion of stored fatty acids to carbohydrates. The peroxisomes in leaves are involved in photorespiration which serves to metabolize aside product formed during photosynthesis.
24) What are the features of a perixosome?
25)Who discovered Perixosomes?
Christian de Duve
Lysosomes and vacuoles
26) What is a contractile vacuole? (knowledge)
a. a membrane bound organelle which is present in all plants and fungal cells
- a saclike cellular organelle that contains vacuoles hydrolytic enzymes
- an organelle involved in osmoreregulation
d. a straight hollow tube of proteins
27) How do contractile vacuoles use osomosis? (Application)
In paramecium, it is surrounded by several canals, which absorbs water by osmosis from the cytoplasm.
28) True or False
Lysosomes come in different shapes and sizes.
True
29) What is the function of lysosomes.
They degrade material taken up from outside the cell and digest components of the cell itself.
