What is the function of the specialized cells in the outer walls of the plant roots?
The specialized cells help to facilitate diffusion of substances into the plant (especially mineral ions and water). However the whole root system serves this process through acrive transport of the mineral ions which creates a diffusion gradient.
Why are cork cells plant cells?
Cork cells are plant cells because they are derived from the cork cambium in woody plants. These specialized cells have thick walls made of suberin that provide support, protect the plant, and prevent water loss. Additionally, cork cells are dead at maturity, unlike most living plant cells.
How are plant cells differ from animials cells?
Plants are unique from animals because plants have a special outer layer over the membrane called a cell wall. also plants have larger vacuoles then animal cells
What is the function of the outer layer of the cheek cells?
The outer layer of the cheek cells is made up of non-keratinized stratified squamous epithelium. Its function is to protect the tissues that lie beneath it from radiation, desiccation, toxins and the invasion by pathogens.
What is the reason why many plants specialized cells that produce strong outdoors?
There are several possibilities. One that comes to mind is that these strong odors may have been developed as secondary compounds which functions as a defensive mechanism against predators.
Why can plants stand in coldness?
Plants function independent of temperatures except in extreme conditions when they are able to adapt themselves with the environment by the modification of the roots,shoots,stem,leaves etc/ or secreting resins to protect the outer layers which itself consists of sclerenchyma cells.
How do sperm cells adapt?
Sperm cells are adapted for their specialized function of fertilizing an egg through several ways. They have a streamlined shape for easy motility, a long tail to aid in movement, and contain enzymes to help penetrate the egg's outer layer. Additionally, sperm cells have a high energy content to sustain their journey to the egg.
What is the name and function of the outer ring cells of a carrot?
The outer ring cells of a carrot are called phloem cells. They are responsible for transporting sugars and other nutrients produced during photosynthesis from the leaves to other parts of the plant, including the roots.
How are epidermal cell designed to perform protective function?
The epidermal cell have cuticle (in plants) or chiten (in animals) on their outer tangential walls to perform protective function.
Why plants cells require cells walls?
There is an outer thick layer in cells of plants called cell wall. This additional layer surrounding the cell membrane is necessary by plants for protection .Plant cells need protection against-1. Variations in temperature,2. High wind speed,3. Atmospheric moister etc
What is the parts of the outer part of the leafs?
The outer part of the leaf is called the cuticle. It is a waxy layer and does not comprise of live cells. It's function is to prevent the leaf from desiccation (drying out).
What is the function of the outer membrane of the chloroplast in plant cells?
The outer membrane of the chloroplast in plant cells acts as a protective barrier, controlling the movement of substances in and out of the chloroplast. It helps maintain the structure and integrity of the chloroplast, allowing it to carry out photosynthesis efficiently.
