Biology 2a- Cells, Organs and Populations

HideShow resource information
Which parts of a cell do animal and plant cells share?
Nucleus, Cytoplasm, Cell Membrane, Mitochondria and Ribosomes
1 of 27
What is the function of the nucleus?
It contains genetic material that controls the activities of the cell.
2 of 27
What is the function of the cytoplasm?
It's where most of the chemical reactions occur, containing enzymes which control them.
3 of 27
What is the function of the cell membrane?
It controls which substances are allowed to move in and out of the cell, as well as holding it together.
4 of 27
What is the function of mitochondria?
It's where most of the reactions for respiration occur.
5 of 27
What is the function of the ribosomes?
These are where proteins are manufactured in the cell.
6 of 27
What other cell parts do plant cells contain?
A rigid cell wall, a permanent vacuole and chloroplasts.
7 of 27
What is contained in a yeast cell?
Yeast is a single-celled microorganism containing a nucleus, cytoplasm, cell membrane and a cell wall.
8 of 27
What makes up a bacterial cell?
Cytoplasm, a cell membrane and a cell wall. They don't have a nucleus, so the genetic material is contained in the cytosplasm.
9 of 27
What is diffusion?
The spreading out of particles from an area of high concentration to an area of low concentration.
10 of 27
How does diffusion through cell membranes work?
Dissolved substances can diffuse in and out of cells, but only very small molecules can move through cell membranes.
11 of 27
How are palisade leaf cells adapted for photosynthesis?
They contain a large number of chloroplasts, most near the top of the cell so they're closer to the light. They also have a tall, thin shape meaning that they have a lot of surface area exposed for absorbing CO2, and that lots can be packed together.
12 of 27
How are Guard Cells adapted for opening and closing pores?
Special kidney shape- open and close stomata. Thin outer walls and thick inner walls. Sensitive to light and close at night. Short of water=flaccid, Lots of water=turgid and plump
13 of 27
How are red blood cells adapted to carry oxygen?
Their concave shape gives a big surface area, they're packed with haemoglobin(the pigment that absorbs oxygen) and they have no nucleus.
14 of 27
How are Gametes specialised for reproduction?
The egg cell holds huge food reserves. Sperm cells have a long tail and streamlined head to help it swim, and there are lots of mitochondria to provide energy.
15 of 27
What are tissues made up of?
Similar cells that work together to carry out a particular function.
16 of 27
What are the main types of tissues?
Muscular Tissue, Glandular Tissue and Epithelial Tissue
17 of 27
What is the function of muscular tissue?
It contracts to move whatever it's attached to.
18 of 27
What is the function of glandular tissue?
It makes and secretes enzymes and hormones.
19 of 27
What is the function of epithelial tissue?
It covers some parts of the body.
20 of 27
What are organs made up of?
It is made up of a group of tissues that work together to perform a certain function.
21 of 27
What are organ systems?
A group of organs working together to perform a particular function, e.g. the digestive system.
22 of 27
What is the digestive system made up of?
The pancreas and salivary glands; produce digestive juices. The stomach and small intestine; digest food. The liver; produces bile. The small intestine; absorbs soluble food molecules. The large intestine; absorbs water.
23 of 27
What are the tissues in plants?
Mesophyll Tissues; where most of the photosynthesis occurs. Xylem and Phloem; transport things like water, mineral ions and sucrose. Epidermal Tissue; this covers the whole plant.
24 of 27
What is the formula for photosynthesis?
Carbon Dioxide + Water----> Glucose + Oxygen
25 of 27
What are the limiting factors of photosynthesis?
Amount of light, amount of carbon dioxide and temperature.
26 of 27
What ways do plants use glucose?
Respiration, making cell walls, making proteins, storing it in seeds, stored as starch.
