Biology - Cell Structure

Cell Membrane

phosoholipid bilayer with embedded proteins 

Cytoplasm

substances between the cell membrane and nucleus. contains cytosol, organelles, cytoskeleton, and other particles.

Cytoskeleton

network of fibers that give support and maintains shape.

Eukaryotic Cell main features

chromosomes, organelles, and cytoplasm

Nucleous makes 

ribosomes 

Chromatin

DNA

Nucleoplasm is the

membrane for the nucleus

Nucleoplasm is the

openings in the nucleas to allow DNA to move in and out 

Another term for nucleoplasm

Nuclear Envelope

Ribosomes are the site of

protein synthesis 

Where are ribosomes found in?

cytoplasm

Where do ribosomes typically reside?

on the endoplasmic reticulum

Ribosomes are found in which cells?

both cells 

Mitochondria is the energy

in form if ATP, cellular respiration

Another term for Mitochondria

powerhouse of the cell

Lysosomes are found in 

animal cells 

What are lysosomes known as?

the garbage disposal 

What do lysosomes do?

Break down substances

What are vacuoles used for?

used for storage and transport

Which cell has a large central vacuole?

plant cells

What features do only plant cells have?

chloroplasts, cell wall, and a large central vaculoe

Chloroplasts has it’s own

DNA

Chloroplasts produce energy through

photosyntesis

Cell Wall gives plants

rigid structure

Endomembrane System explains how

proteins are made and exported from the cell

Ribosomes

Make the proteins 

Endoplasmic Reticulum 

transports proteins (like a highway)

Golgi Apparatus

packages & exports (like a post office)

Vesicles

can fuse with the membrane and transport materials out of the cell

What is the relationship between the vesicle and golgi apparatus?

the golgi apparatus “packages” the proteins into vesicles for “export”
