The cell Flashcards

(9 cards)

1
Q

Describe the structures present in all cells

A
Cells are divided into 2 compartments 
Nucleus
Cytoplasm
Both contain a number of organelles.
Cytosol – Organelles and fluid

Q

What’s inside Nucleus and Nucleolus

A

Nucleus contains DNA, Nucleoprotein and some RNA

The Nucleoli serve as sites for ribosomal RNA synthesis and ribosomal assembly.

Q

Whats structure and role of Endoplasmic Reticulum

A

an interconnecting network of membranous tubules, vesicles, and flattened sacs (cisternae)
Two forms
Rough ER (Studded appearance due to ribosomes)
Smooth ER
Rough ER synthesizes and secretes/packages proteins
Smooth ER is responsible for lipid biosynthesis, membrane synthesis, and repair

Q

Define the role of the cytoskeleton

A

This provides strength and support, while also allowing for cell motility.
Microfilaments– Fine strands of actin( G and F actin subunits also found in non-contractile cells).In the small intestine, Microfilaments form Microvilli.
Microtubules - Larger than microfilaments, can form cilia (9 pairs of microtubules)
