What are the hairs on the leaf of the water fern for?
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.
How is osmosis involved in supplying water for photosynthesis in the leaf?
Because osmosis is related to the movement of water molecules.
What is ligule?
The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs.
What is the biological importance of variegated plants?
Leaves that do not have a uniform colour are called variegated leaves.
How would you recognize the epidermis of a root versus the epidermis of a leaf?
The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
What type of microscope would i use in counting the hairs on the surface of a leaf?
A light microscope would be suitable for counting the hairs on the surface of a leaf. This type of microscope can provide sufficient magnification and resolution to observe and count the hairs effectively.
What are the hairs on the leaf of the water fern for?
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.
What is the purpose of leaf hairs and how do they contribute to the overall function of a plant's leaves?
Leaf hairs, also known as trichomes, serve various purposes in plants. They help reduce water loss by creating a barrier against evaporation, protect the leaf from harmful UV radiation, deter herbivores by making the leaf surface less palatable, and trap moisture and nutrients. Overall, leaf hairs contribute to the overall function of a plant's leaves by aiding in water conservation, protection, and nutrient absorption.
What is the importance of hairs in the body?
Human hairs have touch receptors that wrap around their roots, so they help in tactile sensory reception.
How is osmosis involved in supplying water for photosynthesis in the leaf?
Because osmosis is related to the movement of water molecules.

What is the importance of breathing through your nose and not in your mouth?
The nose hairs help filter the air you breath.
How does the brittle bush adapt to survive in the desert?
in general, brittle bushes in the desert have deep roots to absorb as much water as possible (or is that cacti?) anyway, they have tightly curled leaves that reduce moisture loss. Leaf pubescence (leaf hairs) grow on brittle brush. These leaf hairs reduce the amount of light the plant is able to absorb, therefore limiting the rate of photosynthetic activity.
How would you recognize the epidermis of a root versus the epidermis of a leaf?
The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
What is the usual functions of the epidermal hairs on a leaf?
to hold the moisture in the leaf
How are leaves used as a means to identifying plants?
These things are considered: the shape of the leaves the margin of the leaves - serrated how the leaves are arranged on the stem - alternate, opposite etc if the leaves have hairs how the leaf blade is divided (or not) what the leaf stem is like what the veins of the leaf blade are arranged
