Cell/Living Things Questions and Answers

What is DNA?

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

endoplasmic reticulum (ER)

ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA.

What are prokaryote cells?

a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria

What is a chloroplast?

Chloroplasts are the food producers of the cell. Chloroplasts are the key structure in the process of photosynthesis.

Cytoplasm

Cytoplasm is the fluid that fills a cell.

Golgi apparatus function

a packaging organelle...The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell.

cell wall

cell walls protect the cells, they also allow plants to grow to great heights.

What are eukaryotic cells?

eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.

What are the samll pieces that make up the cell called?

organelles

Cells can also connect to form larger structures called what?

tissue

cell membrane

A cell structure that controls which substances can enter or leave the cell.

What is atp ?

Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

What would happen if one cell were missing?

All cells have a purpose..If you were missing a piece you needed to survive, you would die.

What are all living organisms divided into?

All living organisms on Earth are divided into cells.

Lysosomes

Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things.

Mitochondria

Mitochondria are known as the powerhouses of the cell.

Why do you need all the organelles in a cell?

Organelles are groups of complex molecules that help a cell survive.

What parts makes a plant cell different from an animal cell?

Plant cells have cell walls and chloroplast.

What makes up most of the cell membrane?

Proteins and phospholipids make up most of the membrane structure.

What is RNA?

Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.

Ribosomes a

Ribosomes are the protein builders or the protein synthesizers of the cell.

What is photosynthesis?

The process by which a cell captures energy in sunlight and uses it to make food

cell nucleus

The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction.

What is rhe main concept of Cell Theory?

The main concept of cell theory is that cells are the basic structural unit for all organisms.
