Organelles
What is the cell nucleus?
A mass in the cytoplasm. It is separated from the cytoplasm by a nuclear membrane that contains pores to allow substances to pass between the nucleus and cytoplasm. It is often called the "brain" of the cell because it controls many cell activities and is important in the process of mitosis or cell division.
What does the cell nucleus do?
-Controls cell activities
-Stores DNA for cell division
Which organelle controls cell activity and stores DNA?
The nucleus
What separates the nucleus from the cytoplasm?
A nuclear membrane
Which organelles consists of one or more small, round bodies located inside the nucleus, and are important in cell reproduction?
The nucleolus
What is the nucleolus?
One or more small, round bodies located inside the nucleus, and important in cell reproduction.
Where are ribosomes made?
The nucleolus
What are ribosome made of?
Ribonucleic acid (RNA) and protein.
What are ribosomes?
Ribosomes, made of ribonucleic acid (RNA) and protein, are manufactured in the nucleolus. The ribosomes move from the nucleus to the cytoplasm, where they aid in the synthesis (production) of protein. They can exist freely in the cytoplasm or be attached to the endoplasmic reticulum.
Which organelle can exist freely in the cytoplasm or be attached to the endoplasmic reticulum?
The ribosomes
What do ribosomes aid in?
Protein synthesis
Which organelle aids in protein synthesis?
Ribosomes
Which organelle is made of RNA and protein, is manufactured in the nucleolus, move from the nucleus to the cytoplasm, aid in synthesis of protein, and can exist freely in the cytoplasm or be attached to the endoplasmic reticulum?
The ribosomes
Where is chromatin located?
In the nucleus
What is chromatin made of?
Deoxyribonucleic acid (DNA) and protein.
What do chromatin condense to form?
Chromosomes
How many chromosomes does a human cell have?
46 chromosomes (23 pairs)
How many genes does a chromosome have?
30,000-45,000
What has 30,000-45,000 genes?
Chromosomes
What are chromosomes made of?
Chromatin (DNA and protein)
What are genes?
The structures that carry inherited characteristics.
What are structures that carry inherited characteristics?
Genes
Approximately how many base pairs of DNA does a gene have?
1,000
What has approximately 1,000 base pairs of DNA?
