PLANT TRANSPORT AND PHOTOSYNTHSIS
TISSUES AND ORAGNS OF PLANT
main tissue types: dermal, vascular, and ground tissue.
Each plant organ (roots, stems, leaves)
Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).
TRANSPORT SYSTEM - TRANSLOCATION
Phloem transports sucrose and amino acids up and down the plant.
this happens between where these substances are made (and where they are used or stored
plants because the source of production
the location of photosynthesis is not the same as the site at which nutrients are stored; as a result it is essential that the nutrients be moved throughout the plant via translocation otherwise the food produced in the leave
EVAPORATIONS AND TRANSPIRTATION
EV-happens when a liquid turns into a gas
When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice
When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor.
TRAN-A physiological process in which water evaporates from the leaves of plants
LEAF ADAPTION
Leaves are adapted for photosynthesis and gaseous exchange.
hey are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.
they can result in the leaf losing a lot of water.
The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.
To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.
Plants have two different types of 'transport' tissue, xylem and phloem. These specialised tissues move substances in and around the plan
