ZOOLOGY Flashcards
(28 cards)
It forms the outer boundary of the cell and determines what enters and leaves the cell.
CELL MEMBRANE
DNA and associated proteins are found as chromatin.
NUCLEUS
It consists of RNA and proteins and are sites of ribosomal subunit assembly.
NUCLEOLI
Site of protein synthesis.
RIBOSOMES
It has ribosomes attached and is a major site of protein synthesis.
ROUGH ENDOPLASMIC RETICULUM
Major site of lipid synthesis.
SMOOTH ENDOPLASMIC RETICULUM
Its function is to collect, modify, package, and distribute proteins and lipids produced by the endoplasmic reticulum.
GOLGI APPARATUS
It is a membranebiund sacs that carry substances from the Golgi Body to the cell membrane, where the vesicle contents are released.
SECRETORY VESICLE
It contains enzymes and breaks down phagocytized material.
LYSOSOMES
Major sites of ATP production.
MITOCHONDRION
It supports tge cytoplasm and organelles and involves with cell movements.
CYTOSKELETON
The cell grows larger, copies organelles and makes the molecular building blocks it will need in later steps.
G1 PHASE
The cell synthesizes a complete copy of the DNA in its nucleus.
S PHASE
The cells grow more, makes proteins and organelles and begins to reorganize its contents in preparation for mitosis.
G2 PHASE
It consists phospholipid bilayer.
CELL MEMBRANE
It is the central control of the cell.
NUCLEUS
Cell starts to break down some structure and build others up, setting the stage for division of the chromosomes.
EARLY PROPHASE
Mitotic spindle begins to capture and organize the chromosomes.
LATE PROPHASE / PROMETAPHASE
Chromosomes starts to condense.
EARLY PROPHASE
Mitotic spindles begin to form and the nucleolus disappears.
EARLY PROPHASE
Nuclear envelope breaks down and some microtubules start to capture chromosome.
LATE PROPHASE / PROMETAPHASE
Spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
METAPHASE
All chromosome alig at the plate.
METAPHASE
What is this attached to microtubules from opposite spindle poles.
KINETOCHORES
