Bio means life; biology is the study of life and a biography is the story of someone's life.
Chloro means green, as in chlorophyll, which is found in green plants.
Lol it wouldn't let me edit before, sry :)
Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.
<h3><u>Explanation:</u></h3>
Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are
A. The outer capsule.
B. The middle cell wall.
C. The inner cell membrane.
The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.
The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.
The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.
Sugar(glucose) and oxygen.
Answer:
Nutrition
Explanation:
Nutrition provides the raw materials for tissue repair.
hopefully this helps :)
Explanation:
there are a couple of environmental factors that affect the rate of transpiration. they include:
I) wind:in a windy environment there is easy movement of moisture hence it does not accumulate on the leaf surface. this helps to increase diffusion gradient between the intercellular spaces in the leaf and in the environment there4 the rate of transpiration is increased. in a calm environment moisture accumulates on the surface of a leaf there4 reducing the diffusion gradient there4 reducing the rate of transpiration
ii) atmospheric pressure :in low lands there is high atmospheric pressure than in the highlands. the more the atmospheric pressure the more the pressure exerted on the cells of the leaves there4 reducing the rate of transpiration.
iii) humidity:the more the humidity in the atmosphere the less the rate of transpiration. this is due to low diffusion gradient due to accumulation of water vapour on the surface of the leaf
iv) temperature:a rise in temp increases the water vapour holding capacity of air in the air spaces within the spongy mesophyll layer. the water vapor pressure in the intercellular spaces increases causing an increase in diffusion gradient between the intercellular spaces and the environment there4 increasing the rate of transpiration. decrease in temp decreases the water vapor holding capacity in the intercellular spaces there4 diffusion gradient is lowered there4 reducing the rate of transpiration.
