3. What is the location and function of Meristematic tissue?

It is primarily located in the flowers of plants. Its function is to store nutrients for the plant.

It is found in the apical bud, auxiliary bud, root tip and cambium regions it function is that it is a growth tissue so it undergoes mitosis in order to give rise to new plant cells that allow the plant to grow in length and width and give rise to the different organs

It is only found in the leaves and stems of plants. Its function is to provide structural support to the plant.

It is found in the roots and branches of plants. Its function is to regulate water uptake in plants.

4. What is the location and function of Epidermal tissue in plants?

It is located in the roots of the plant. Its function is to conduct photosynthesis.

It is found in the inner layer of the plant stems. Its function is to store excess water.

It is found in the outer layer covering the entire plant Its function is that it is used for protection to the underlying tissues against infection, injury and waterloss

Epidermal tissue is found in the flowers of the plant. Its function is to aid in reproduction.

Epidermal tissue is a protective layer covering the entire plant to guard against various external threats. Its main function includes protection against infection, injury, and prevention of water loss.

Explanation

Epidermal tissue is a protective layer covering the entire plant to guard against various external threats. Its main function includes protection against infection, injury, and prevention of water loss.

5. What are the three modifications of epidermal cells?

Meristem cells, Lenticels, and Sclerenchyma

Stomata , Root hairs and Trichomes

Guard cells, Cuticle, and Xylem vessels

Palisade cells, Collenchyma, and Phloem fibers

Epidermal cells undergo various modifications to serve specific functions in plants. Stomata regulate gas exchange, root hairs aid in water and nutrient absorption, and trichomes provide protection against herbivores and reduce water loss through transpiration.

Explanation

Epidermal cells undergo various modifications to serve specific functions in plants. Stomata regulate gas exchange, root hairs aid in water and nutrient absorption, and trichomes provide protection against herbivores and reduce water loss through transpiration.

6. What are the functions and locations of the three modifications of epidermal cells?

Stomata- found in the aerial parts of the plant and not in the root region and its function is that it allows for gaseous exchange Root hairs - they are found in the root and their function is that they increase surface area to absorb water and minerals Trichomes - they are found in leaves and young stems and their function is that they reflect light, protection and they retain moisture

Guard cells- found in the roots and their function is to store excess water.

Cuticle- found in stems and its function is to transport nutrients within the plant.

Xylem vessels- found in leaves and their function is to provide structural support to the plant.

Epidermal cells within plants can undergo modifications to serve various functions depending on their location. Stomata, root hairs, and trichomes play crucial roles in the overall health and functionality of the plant by aiding in processes like gaseous exchange, absorption of water and minerals, light reflection, protection, and moisture retention.

Explanation

Epidermal cells within plants can undergo modifications to serve various functions depending on their location. Stomata, root hairs, and trichomes play crucial roles in the overall health and functionality of the plant by aiding in processes like gaseous exchange, absorption of water and minerals, light reflection, protection, and moisture retention.

7. Where is the location of sclerenchyma?

It is found primarily in the phloem tissue.

It forms a cap ontop of the vascular bundle , around the veins in leaves and amongst vascular tissue

It is present in the stomata of the leaf surface.

It is located in the epidermal layer of plant stems.

Sclerenchyma is a type of supportive tissue in plants that provides structural support. It is commonly found in specific locations within the plant's structure, forming a cap on top of the vascular bundle, around the veins in leaves, and amongst vascular tissue.

Explanation

Sclerenchyma is a type of supportive tissue in plants that provides structural support. It is commonly found in specific locations within the plant's structure, forming a cap on top of the vascular bundle, around the veins in leaves, and amongst vascular tissue.

8. What are the two types of sclerenchyma?

Sclerenchyma fibres and sclereids ( stone cells)

Xylem fibers and phloem fibers

Collenchyma fibers and parenchyma cells

Epidermal cells and guard cells

Sclerenchyma tissues are known for providing structural support in plants. Sclerenchyma fibers are long, slender cells, while sclereids (stone cells) are shorter and more irregular in shape.

Explanation

Sclerenchyma tissues are known for providing structural support in plants. Sclerenchyma fibers are long, slender cells, while sclereids (stone cells) are shorter and more irregular in shape.

9. What are some characteristics of fibres?

-they are elongated with tapered ends- they have a thick cell wall- they have lumen

-they are short and stubby- they are hollow- they are transparent.

-they are round in shape- they have a thin cell wall- they contain chlorophyll.

-they are rigid and inflexible- they lack a cell wall- they are translucent.

Fibres are known for their elongated shape, thick cell wall, and lumen, which are key characteristics distinguishing them from other cellular structures.

Explanation

Fibres are known for their elongated shape, thick cell wall, and lumen, which are key characteristics distinguishing them from other cellular structures.

10. What are some characteristics of sclereids (stone cells)?

- primarily found in animal tissues

- found in certain fruits eg. pears and the shells of nuts- has a circular and irregular shape- has a thick cell wall- has lumen

11. Where is xylem located within a plant?

Xylem is found in the stele ( centre) of the root; vascular bundles in the stem and the veins in leaves

Xylem is only present in the flowers of plants.

Xylem is exclusively located in the roots of plants.

Xylem is found in the phloem tissue of plants.

Xylem is a type of vascular tissue that transports water and nutrients throughout a plant. It is specifically located in the stele of the root, the vascular bundles in the stem, and the veins in leaves, playing a crucial role in plant physiology.

Xylem is a type of vascular tissue that transports water and nutrients throughout a plant. It is specifically located in the stele of the root, the vascular bundles in the stem, and the veins in leaves, playing a crucial role in plant physiology.

12. What four tissues make up xylem?

- cork cells - guard cells - xylem ray cells - epidermal cells

-sclerenchyma fibres- parenchyma- vessels- tracheids

- cork cambium - sieve tubes - companion cells - pit cells

- phloem - meristem - epidermis - collenchyma

Xylem is composed of various tissues including sclerenchyma fibres, parenchyma, vessels, and tracheids, which are responsible for conducting water and minerals in plants.

13. What are the characteristics of vessels?

Vessels have a solid structure with no lumen or cell wall.

Vessels have a thin cell wall without any lumen or cross walls.

Vessels have lumen, a thick cell wall and broken down cross walls. Walls can be thickened in four different ways ; spiral, annular, reticulate and pitted

Vessels are made up of only cross walls with no lumen or cell wall.

Vessels are a type of plant cell structure that have specific characteristics including lumen, thick cell walls, and broken down cross walls with different thickening patterns.
