Which Best Describes why Plant cells have chloroplasts and animal cells do not A- Plant cells need chloroplasts to make DNA because most plant cells do not contain a Nucleus

B- Plant Cells need chloroplasts to make food because most plants cannot move to get there food on their own

C- I dont know

D- Plants cells need Chloroplasts to move materials in and out of the cell because most plants cells do not Contain a Cell Membrane

B

Explanation:

Plant cells need chloroplast to make food because most plants cannot move to get their food on their own

D

Explanation: Because The Chloroplast is the Gate to move waste out of the cell and nutrients into the cell. Most plants do not contain a cell membrane.

wheres the options ? : (

explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
