Transport in plants (P2C9) Flashcards
What is the function of the epidermal tissue?
The epidermal tissue covers the outer surfaces of the plant for protection.
What is the function of the palisade mesophyll?
The palisade mesohyll is the main site of photosynthesis for a leaf.
What is the function of the spongy mesophyll?
The spongy mesophyll allows gases to diffuse through the leaf at a greater rate.
What is the function of the xylem vessels?
The xylem vessels transport water and minerals through the plant, from the roots to the leaves.
What is the function of the phloem vessels?
The phloem vessels transport dissolved food materials through the plant.
What is the function of the meristem tissue?
The meristem tissue produces new cells for growth.
What is the mesophyll of a leaf?
The mesophyll of a leaf is the section between the lower and upper epidermis.
Where is the palisade mesophyll found in a leaf?
The palisade mesophyll can be found high up inside the leaf, just underneath the upper epidermis but still inside the mesophyll.
Where is the spongy mesophyll found in a leaf?
The spongy mesophyll composes the lower 2/3 of the mesophyll, reaching from below the palisade mesophyll to the lower epidermis.
Where is the meristem tissue found in a plant?
The meristem of a plant is found at the tip of roots and shoots, since that is where the new cells will be needed.
How do plants gather minerals?
Plants gather minerals through the roots, within water.
Which vessel carries water up from the roots to the leaves?
Water is carried by the xylem vessel within a plant.
What is transpiration?
Transpiration is the loss of water from the leaves.
What are the stomata of a plant?
The stomata of a plant are gaps through which gases can diffuse in and out.
What cell type controls the opening and closing of stomata?
Stomata are closed and opened by adjacent guard cells.
