Answer:

Eukaryotic Cell organelles

B. A Mitochondira.It is often called as the energy reservoir of a cell..Its a site of cellular  respiration.In Eukaryotes the respiratory pathways are either aerobic or anaerobic respiration depends upon the nature of a species.The number of mitochondria varies depends the energy requirements to a cell.The mitochondria is membrane bound organelle double inner and outer membrane.These layers are made up of phospholipid bilayers and proteins.The inner is folded called cristae.The regions within the cristae is called mitochondrial matrix here the citric acid cycle .Krebs cycle,glycolysis takes place In over all cycles 38 ATP is generated.

C.A lysosomes: It is absent in plant cells but present in animals cell also termed as waste disposal. Enzymes of lysosomes helps in the breakdown of proteins ,lipids  ,polysaccharides ,nucleic acids and damaged organelles.The lysosomes breaks down macromolecules and contains plenty of enzymes.

D.Endoplasmic reticulum: It’s a flattened sac like structure within the cytoplasm of a cell. It performs various functions but more specifically it synthesizes and modifies and transport proteins. There are two types of ER rough Er and smoothER .The RER synthesize proteins transports by the ribosomes.and the SER synthesize lipids.

Function in the cell cycle. Explain why interphase is important before mitosis begins.
Luda [366]

Answer:

During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
