How are plant cells adapted to carry out their functions?
Plant cells have a thick waxy cuticle which is transparent to allow sunlight to pass through and it also minimises water loss. There are air spaces in the spongy mesophyll which allows gas exchange to occur (e.g. allows carbon dioxide to enter for photosynthesis to occur).
The vascular tissue (xylem and phloem) run through veins in the leaf, which also provide structural support. The thickness, shape, and size of leaves are adapted to specific environments. Each variation helps a plant species maximize its chances of survival in a particular habitat.
How are epidermal tissues adapted to their function?
The epidermis consists of the upper and lower epidermis; it aids in the regulation of gas exchange via stomata. The epidermis is one layer thick, but may have more layers to prevent transpiration. The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation.

What are the tissues found in the plant body How are they organized in each vegetative organ?
Each organ is made up of cells organized into tissue systems: dermal, vascular and ground. One way the vegetative organs (leaves, stems and roots) differ from each other is in the distribution of the tissues. Some of the tissues are composed mostly of a single cell type; these are called simple tissues.
What are the functions of the tissues in a leaf?
Transport. Xylem tissue delivers water from the roots to the leaf, and phloem tissue transports glucose away from the leaf. These tissues form vascular bundles in the plant.

Read about primary growth of plants. What process is most important in the expansion of plant cells? Water uptake typically accounts for 90% of the expansion of growing plant cells.
Which function is mostly performed in the fleshy tissue parts of a plant rather that in the tissues that make up the upper layer of leaves?
Storage function is commonly performed in the part of the fleshy tissues parts of plant. Apart from that the tissues which make up the part of the upper layers of the laves.
How does dermal tissues help plants on a hot day?
Dermal tissue helps plants on a hot day by: It has a waxy material that prevents the loss of water to the environment. Because, it has waxy materials that help to prevent the loss of water and raises the guard cells. This should highlight in open to prevent the loss of water to the environment.
How does dermal tissue help plants on a hot day quizlet?
How does dermal tissue help plants on a hot day? It has a waxy material that prevents the loss of water to the environment.
How does the organization of cells tissues and organs determine structure and function in plant animal systems?
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Which tissue helps in photosynthesis?
Leaf mesophyll composed of parenchyma tissue. The elongated palisade parenchyma contains the largest number of chloroplasts per cell and is the primary site of photosynthesis in many plants.
How do animal and plant tissues perform their roles?
Cells which are similar in structure group together to form tissues performing a particular function. Tissues form organs which combine to allow organisms to exist. Plant and animal cells have structures related to their functions. Plant tissues are broadly divided into Dividing or Meristematic and Permanent tissues.
What are the 3 main functions of a leaf?
Main functions of leaf are: (a) The leaves make food for the plant by photosynthesis. (b) The leaves carry out the process of respiration in plants. (c) The leaves get rid of excess water from the plant through transpiration.
How are tissues in a leaf arranged to form an effective organ for photosynthesis?
Large surface area Most leaves are broad and so have a large surface area allowing them to absorb more light. A thin shape A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.
What is a plant tissue called?
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis ” Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue ” The primary components of vascular tissue are the xylem and phloem.
Why is translocation in plants important?
Translocation in plants takes place by vascular tissue called phloem. Translocation is essential because, without it, the food prepared by the leaves cannot reach other parts of the plant. (b) Food is transported to stem, root and all other storage regions of plants.
How do substances move through a plant by transpiration and translocation?
The water evaporates from the stomata on the leaves. The upward pull of water is by capillary action due to the cohesion-tension theory. Translocation is the movement of organic materials such as sucrose from source to sink. This is often a movement of sucrose from the leaves to other areas of the plants.
