Bioscience - Cells 2020

The cell membrane is made up of …..
Phospholipids, proteins, cholesterol, glycolipids and or glycoproteins
1 of 31
The lipids of the cell membrane
Are hydrophobic (hate water)
2 of 31
The cell
Is the basic unit of life
3 of 31
The intracellular structures are collectively called
4 of 31
The instruction centre for the cell’s activities is
The nucleus
5 of 31
Is a multistage mechanism that requires metabolic energy for bringing materials into the cell
6 of 31
Simple Diffusion refers to the
The movement of particles from an area of their high concentration to one of a lower concentration
7 of 31
Facilitative diffusion
Works in the same way as simple diffusion but with the inclusion of special carrier proteins in the cell membrane without the need for ATP
8 of 31
The cell component that is responsible for the connection of the correct sequence of amino acids to form chains (proteins) is called
The Ribosome
9 of 31
The DNA of a cell instructs the protein synthesis apparatus by
Replicating to produce a smaller single strand molecule called messenger RNA, for the purpose of delivering instructions for protein synthesis
10 of 31
The mitochondria has its own
DNA, RNA and ribosomes
11 of 31
The cell moves by use of
The cytoskeleton shifts its components from one area of the cell to another creating consistency changes in the cytoplasm
12 of 31
The Golgi apparatus is responsible for
Completing the peptide chain (protein chain) by adding other molecules
13 of 31
The site of ATP synthesis is
The mitochondria
14 of 31
The sites of ATP synthesis require
Oxygen and Glucose
15 of 31
The Rough Endoplasmic Reticulum
A series of cytoplasmic transport channels dotted with ribosomes
16 of 31
The main purpose of the cell membrane is ….
To enable the cell to be selective in terms of what particles are allowed into the cell
17 of 31
Proteins in the cell membrane are NOT
Engulfing facilitators for large particles
18 of 31
Osmosis is best described as
The movement of water molecules across a semipermeable membrane from an area of higher water concentration to one of lower water concentration.
19 of 31
Active transport is best described as
Uses ATP to drive substances across a biological membrane against the concentration gradient
20 of 31
Pinocytosis is …… (read carefully)
The bulk flow of aqueous (watery) material across a membrane by the invagination of sections of the membrane (engulfing)
21 of 31
Exocytosis is ……
The expulsion of certain materials from the cell for secretion, release or excretion of waste, using vesicle formation and release into the extra cellular space.
22 of 31
Cell components that are responsible for the sculpting or removal of redundant tissues are called
23 of 31
The nucleus contains all but
24 of 31
The building blocks of DNA and RNA are called
Nucleic acids
25 of 31
The nucleolus
Makes ribosomes
26 of 31
The nuclear envelope that surrounds the nucleus is ……
Just the same as the whole cell perimeter membrane, but double like that of the mitochondria, but has more stringent security gated channels and pores
27 of 31
A chromosome is
A carefully folded DNA strand
28 of 31
Cells divide to make more of themselves for both tissue growth and cell replacement purposes. The process is called…
29 of 31
Cilia are
Cytoplasmic outgrowths that resemble hairs, they have rhythmic motion designed to waft particles or fluids along channels
30 of 31
Cells have
A and B are correct (A programmed life span & Die when they are starved of nutrients and or oxygen)
