What are the characteristics of living organisms?
Movement, reproduction, sensitivity, growth, respiration, exretion, nutrition
1 of 25
name three parts of an animal cell
cytoplasm, nucleus, cell membrane
2 of 25
what are the two main purposes of chloroplasts?
carry out photosynthesis and store carbohydrates such as starch or sucrose
3 of 25
Function of cytoplasm?
wjere most of the chemical reaction happens
4 of 25
Function of nucleus?
contains genetic material which controls the cells activites
5 of 25
Function of cell membrane?
conrols movement of substances in and out of the cell
6 of 25
Function of Mitochondria?
wherre most energy is released in respiration
7 of 25
Function of Ribosomes?
Where protein synthesis happens
8 of 25
Function of Chloroplasts?
Absorbes light for photosynthesis
9 of 25
Function of Cell wall?
stengthens the cell and supports the plant
10 of 25
Function of Permenant vacuole?
filled with cell sap to keep the cell turgid

what is the word and symbol equation for aerobic respiration?
glucose + oxygen --> carbon dioxide + water (C6H12O6 + 6O2 → 6CO2 + 6H2O
12 of 25
what is the word and symbol equation for anaerobic respiration?
glucose --> lacitc acid (C6H12O6 → 2C3H6O3)
13 of 25
Define homeostasis
homeostasis is the process the body uses to maintian a constant internal enviroment

what is diabetes type 1?
Diabetes is a condition in which the blood glucose levels remain too high. It can be treated by injecting insulin.
16 of 25
what is diabetes type 2?
Type 2 diabetes is caused by a person’s body becoming resistant to insulin. It can be controlled by diet and exercise. There is a link between rising levels of obesity and increasing levels of Type 2 diabetes.

What is DNA?
They carry the genetic code that determines the characteristics of a living organism.
18 of 25
What are genes?
A gene is a section of DNA that codes for a specific protein
19 of 25
What are chromosomes?
The cell’s nucleus contains chromosomes. These are long threads of DNA, each made up of many genes.
20 of 25
What are alleles?
There are pairs of chromosomes in the nucleus of a body cell. The chromosomes in a pair carry the same genes in the same places. But there are different versions of the same gene.
21 of 25
Define dominant allele
A dominant allele is always expressed, even if the individual only has one copy of it. For example, the allele for brown eyes is dominant. You only need one copy of it to have brown eyes
22 of 25
Define resecive allele
A recessive allele is only expressed if the individual has two copies of it and does not have the dominant allele of that gene. For example, the allele for blue eyes is recessive. You need two copies of this allele to have blue eyes.
23 of 25
What does mitosis produce? and why?
two genetically identical cells in which the number of chromosomes is the same as in the original cell.growth repair to damaged tissue replacement of worn-out cells
24 of 25
What does meiosis produce? and why?
Meiosis produces four genetically different haploid cells. Unlike mitosis, meiosis is a reduction division used for production of gametes for sexual reproduction
