Question 1

The cell is the basic unit of life in all organisms. Like humans and animals, plants are also composed of several cells

Answer 1

Plant Cell

Question 2

are eukaryotic cells with a true nucleus along with specialized structures called organelles that carry out certain specific functions.

Answer 2

Plant Cell

Question 3

It is a rigid layer which is composed of polysaccharides cellulose, pectin and hemicellulose. It is located outside the cell membrane

Answer 3

Cell Wall

Question 4

The plant cell wall is also involved in protecting the cell against mechanical stress and providing form and structure to the cell. It also filters the molecules passing in and out of it.

Answer 4

Cell Wall

Question 5

This round organelle is in the center of the cell. It controls all the activities of the plant cell.

DNA is house within the

Answer 5

Nucleus

Question 6

It is the part that produces food in a plant cell.

Contain the enzyme necessary for photosynthesis plus the green pigment chlorophyll.

Contain small amount of DNA and few ribosomes

Answer 6

Chloroplast

Question 7

help maintain water balance in plant cells.

The storage part of the cell.
- Contains a variety of

materials; water, dissolved salts, ions, pigments and waste product

It occupies 90% of the cell of mature plants

Answer 7

Vacuole

Question 8

The cell’s collecting and packaging center

It is the part that helps process and

package proteins and lipid molecules in the plant cell.

It collects and processes materials that are to be exported from the cell (e.g.

polysaccharides that make up the cell wall)

Answer 8

Golgi Apparatus

Question 9

It is the power house of the plant cell.

site of cellular respiration in which fuel molecules are broken down into carbon dioxide and water with the release of energy (Adenosine triphosphate - ATP) Contain few amounts of DNA and few ribosomes

Answer 9

Mitochondria

Question 10

The manufacturing center of the cell

Two types of it are smooth endoplasmic reticulum and rough endoplasmic reticulum.

extensive network of parallel membranes that extends throughout the cell’s interior

Answer 10

Endoplasmic Reticulum

Question 11

The component of plant cell important for structure and cell. movement

CYTOSKELETON

2 fibers Microtubules and Microfilaments

Answer 11

Cytoskeleton

Question 12

The physical boundary that regulates the flow of materials into and out of the cell

• is a selective barrier

Answer 12

Plasma Membrane

Question 13

are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules.

Lysosomes are an important cell organelle found within eukaryotic animal cells. Due to their peculiar function, they are also known as the “suicide bags of the cell

Answer 13

Lysosomes

Question 14

These are live undifferentiated cells found in a variety of places of the plants’ bodies.

They participate in several mechanisms of the plan including photosynthesis, food storage, secretion of waste materials.

The experimental observation indicated that they appear green.

Answer 14

Parenchyma cells

Question 15

Two Types of Parenchyma Cells

Answer 15

Palisade parenchyma -Ray parenchyma

Question 16

cells are columnar elongated structured cells found in a variety of leaves, lying below the epidermal tissue. Palisades are closely linked cells in layers of mesophyll cells found in leaf cells.

Answer 16

Palisade parenchyma -

Question 17

has both radial and horizontal arrangements majorly found within the stem wood of the plant.

Answer 17

Ray parenchyma

Question 18

They are elongated cells found below the epidermis and/or in young plants on the outer layers of their stems and leaves.

They become alive after maturing up and are derivatives of the meristems and they are found in the vascular and/or on the plant stem corners.

They occur in the peripheral region of the plant and are not found in

the plant roots. In experimental observation, they

appear red

Answer 18

Collenchyma cells

Question 19

Collenchyma cells types

Answer 19

Angular collenchyma.

Lamellar collenchyma.

(C) Annular collenchyma.

(D) Lacunar collenchyma.

Question 20

The cells appear to have an

angle and a polygonal shape. The cells are thickened at the corners of the cell The cells do not have intracellular spaces since they are closely packed together They are the most common type of collenchyma

Answer 20

Angular Collenchyma

Question 21

The cells are thickened on the periphery making them appear tangentially arranged in rows They are closely packed together and therefore they don’t have intracellular spaces

Answer 21

Lamellar Collenchyma

Question 22

The walls are uniformly thickened.

The cells appear to be circular in shape

Answer 22

Annular Collenchyma

Question 23

These are cells are formed spaciously leaving intracellular spaces between each other. The cell wall thickens around the intracellular spaces They appear spherically shaped They are formed and found in the walls of fruits

Answer 23

Lacunar Collenchyma

Question 24

These are collenchyma cells that have an agent of the cell wall that plays a major role in hardening its cell wall. Therefore, these are mature Collenchyma cells with a secondary cell wall, over the primary cell wall.

They are found in all plant roots and they are important in anchoring and giving support to the plants.

Answer 24

Sclerenchyma cells

Question 25

Two Types of Sclerenchyma cells

Answer 25

Fiber sclerenchyma cells

Sclereid sclerenchyma cells

Question 26

are complex cells found in the vascular tissues of plants, mostly in woody plants.

The primary function of the xylem ceils is to transport water and soluble nutrients, minerals and inorganic ions upwardly from the roots of the plants and its parts.

Answer 26

Xylem Cells
