1. CELL REVIEW
1. Look at the cell diagrams and answer the questions.
1. Are they eukariotyc or prokaryotic cells? Why?
2. Are they animal cells or plant cells?
3. Write the names of the organelles.
2. Which type of cell is it? Do you remember the name of any
organelles?
2. 3. Write the terms that correspond to the following definitions.
1. It is the total set of genes in a cell.
2. It is the outer covering of a cell, like a skin around it that covers it completely. It
regulates the substances exchanged between the inside and the outside of the
cell.
3. This is where proteins formed in the ribosomes are stored and processed.
4. It is the part of a cell where energy is obtained. It is also responsible for cell
respiration.
5. A thick, rigid part of plant cells that surrounds the plasmatic membrane and
provides support and protection.
6. It is the inside of the cell. It is a gelatinous, semi-transparent fluid where many of
the chemical reactions of the cell take place.
7. The smallest units of life.
8. It contains the genetic material of the cell.
9. Small structures in the cytoplasm responsible for cell functions.
10.Organelles that store a green pigment called chlorophyll and where
photosynthesis takes place.
11.Cells with no nucleus or nuclear membrane.
12.They are like bags, surrounded by membranes, where storage or waste
substances accumulate, mainly water.
13.Cells which have a nucleus, separated from the cytoplasm by the nuclear
membrane.
4. Write the terms that correspond to the following definitions.
a. The structural and functional units of all living things.
b. Small simple cells in which the genetic material is loose in the cytoplasm.
Bacteria are made up of this type of cells.
c. They contain a pigment that absorbs the Sun’s energy to elaborate organic
matter during photosynthesis.
d. This is the endoplasmic reticulum, which functions as the cell’s transport
system.
e. They take up most of the space in plant cells. They are also in animal cells,
but they are smaller.
f. They are small structures in the cytoplasm responsible for respiration,
making and storing nutrients, etc.
g. The chemical units of hereditary information carried by a cell.
h. It is made of cellulose and gives the plant cell its shape and strengthens it.
i. It contains the hereditary information of living things, which is passed from one
generation to the next. It is usually found on one side in plant cells.
j. Thin layer that separates the inside of the cell from its surrounding
environment.
k. Cells in which the genetic material is enclosed in a structure called the
nucleus. Algae, protozoa, fungi, animals and plants have this type of cells.
l. It contains the nucleus, organelles, mitochondria, vacuoles, etc.
m. It is the part of a cell where nutrients turn into energy.
