Brainlies asap! : ) describe the structure and function of the endoplasmic reticulum (both rough er and smooth er). v

Smooth ER

- Smooth ER is an arrangement of tubules, vesicles and sacs.

- The size and structure of the SER varies between the cells.

- The SER can change within a cells lifetime to allow the cell to adapt to changes in its function and requirements.

- There are no riobsome's attached to the membrane surface.

- The SER is connected to the nuclear envelope

Rough ER

- Rough appearance because it has ribosomes

-Function: Site of protein synthesis - thus is why it has ribosomes

- Lined with ribosomes

- Modifies proteins that are being transported

- Made of RNA and protein

- Assemble proteins based on instructions from DNA

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
