Cell Structure and Transport Flashcards
(74 cards)
How do you work out the Magnification?
Size of image divided by the real size.
How do you work out a question. Eg, A=7.5 and M=2000.
A=7.5 M=2000 I=? M x A = I 2000 x 7.5 = 15000
What does the Nucleus do?
What does the Cytoplasm do?
What does a Cell membrane do?
The nucleus controls all the activities of the cell.
The Cytoplasm is a liquid gel where most reactions happen.
The Cell membrane controls the passage of substances such as glucose.
What does the Mitochondria do?
What is the Ribosome?
The mitochondria is the structure of the cytoplasm where aerobic respiration takes place.
The Ribosomes are where protein synthesis takes place.
What is the cell wall?
What is Chlorophyll?
The cell wall strengthens the cell and gives it support.
The Chlorophyll absorbs light, turns the plant green.
What is Chlorophyll?
Chlorophyll absorbs the sunlight. Also turns the plant green
What is a permanent vacuole?
A permanent vacuole keeps the cell rigid to support the plant.
What are Eukaryotic cells?
Eukaryotic cells are quite complex. They contain more cells. Plant and animal cells have these.
What are prokaryotic cells?
Prokaryotic cells are quite simple. They contain less cells than eukaryotic.
What is magnification?
Magnification is the zoom and how big or small the cell is.
What is resolution?
Resolution is how clear an image is. HD is another word for resolution.
What does the nerve cell do?
The nerve cell send a message using special transmitter chemicals. They contain lots of mitochondria.
What do muscle cells do?
Muscle cells contain many mitochondria to transfer energy needed for chemical reactions for cells to contract and relax.
What do sperm cells do?
Sperm cells contain genetic information from the male person. They move through water or the female reproductive system to reach an egg.
What do photosynthesis cells do?
Photosynthesis cells contain green structures called chloroplasts. These cells make food for the plant.
What are do root hair cells do?
You find root hair cells close the tips of growing roots. Plants need to take in lots of water. Root hair cells help them take up water and mineral ions more efficiently.
What do Xylem cells do?
Xylem is the transportation of the tissues. It also carries water and minerals from the root hair cells to the highest leaves and shoots. It also helps support the plant.
What are Phloem cells?
Phloem cells is the transportation of food made by photosynthesis around the body if the plant. They form tubes like Xylem cells but do not die. The dissolved food can move up and down the phloem tubes to where it is needed.
What cell (Eukaryotic or prokaryotic) is bigger.
Eukaryotic cells are bigger than prokaryotic cells. They are 10um - 100um. Prokaryotic is 1um.
How big is an animal cell?
10um
How big is a plant cell?
100um
How much bigger is a plant cell to an animal cell?
Remember: 100
—- =
10
1
A plant cell is 10 Bigger than an animal cell.
How do you get from KM to M?
You need to times the KM by 1000 to get to metres.
How do you get from MM to M?
You divide the MM to M
