Cell Organelles Quiz

Transport Vesicle function

Move molecules around the cell

What do transport vesicles move?

Protiens, carbs, and lipids

Transport Vesicles structure

Small, circular cellular container, membrane enclosed

Where is the rough ER located?

next to the nucleus, attached to nuclear envelope

Rough ER structure

series of highly folded membranes suspended in the cytoplasm. ribosomes are attached on the outside

Rough ER function

Production and use of proteins, synthesize new enzymes and proteins

animal vacuole function

Store water, ions, waste, nutrients, maintain water balance, get rid of waste

How many vacuoles does an animal cell have?

many small vacuoles

animal vacuole structure

membrane made of phospolipids and embedded proteins

Chromoplasts function

store and synthesize pigments, assists in photosynthesis, and produce plant hormones

chromoplasts structure

made of ribosomes, circulate DNA, and an internal membrane, contains keratniod crystals

Chromoplasts importance

Create color in flowers that attracts pollinators

nucleolus structure

inside the nucleus, spherical shape, made of DNA, RNA, and proteins

Nucleolus function

produces ribosomes, transcribe RNA genes, ribosomes are responsible for protein synthesis

secretary vesicle function

takes molecules out of a cell, extreets toxins, transmit signals, break down food, prevent material buildup

secretary vesicle structure

enclosed by a membrane of lipid bilayers (clusters of hydrophilic heads and hydrophobic tails)

intermediate filaments structure

made of intertwined chains of protein molecules, rolled up, strong and malleable

intermediate filaments function

binding organelles to the cytoplasm and cell membrane, binding two areas of the cell membrane to maintain cell shape, holds nucleus in place

Nucleoplasm structure

contains DNA polymerse, sugar, amino acids, matrix+chromatin, surronded by nucleur envolpe, covers the nucleus.

nucleoplasm function

suspend organelles in the nucleus, help it perform it's functions, contains genetic material for cytoplasm, helps cell replication

Flegella function

stimulate movement in signular cell organisms and sperm, allows sperm cells to get to eggs, baterial movement

Golgi complex structure

Consist of stacked citsernee and enclosed membranes

Golgi complex functions

Modify proteins, sort protiens, process lipids, make lysosomes, release proteins and lipids

Lysosomes function

Dispose of waste, help mantain homeostatsis, retire old organelles, combats viruses (by digesting them) repair cell membrane

Lucoplast function

Stores and synthesizes nutriants, starch, lipids, and proteins, can become chlorplasts or chromoplasts

Lucoplast structure

made of colorless plastids, smoth membrane, dense intertior

Plant vacuole function

Nurtraint storage, water regulation, waste managament, defense mechinaces, ceullar growth, provide plants with structure

Nucleus structure

Membrane bound organelle that contains the chromosomes, biggest organelle

Nucleus known as the

"Control Center"

Nucleus functions

Store gentic information, DNA replication and transmission, house cell genome, regulate other organelles such as ribosomes

Ribosome structure

2 subunits, made of ribosomal RNA and proteins: the large and small subunit

Ribosome function

protein synthesis

Cytoplasm function

provide shape to cell and encompasses other organelles, assit in metabolic activities

mitochrondria structure

double membrane, contains ribosomes and DNA

Mitochrondria Function

energy production (ATP), regulate metabolism? store calcuim, produce an iron compound, initiate cell growth

cell wall structure

three layers

Cell wall function

rigid against turger pressure, provide structure

cytoskelton function

keeps cell structure

cytoskelton structure

microtubules, microfilaments, intermediate filaments (three proteins)

Chroloplasts function

create glucose, carbs, lipids, and atp, photosynthesis, and creating oxygen. Give plants energy and animals oxygen

chloroplasts structure

double membrane

microtubes function

detirmine cell shape and structure, cell movement, and transport, split chromosomes during mitosis, gives route for intercelluar transport

Microtubles structure

part of cytoskeleton
