How tall do indica plants get?
Outdoors, indica plants are unlikely to grow taller than six feet (two meters), and indoor plants usually grow three feet (one meter) or less. Indica strains tend to spread out wide like a bush, with vigorous branching.
How do I make my pothos grow thicker?
You may use compost or liquid seaweed solution for fertilizing the soil at least once or twice a month. This will boost the foliage growth and make the plant look heavier and fuller. For a solid fertilizer, sprinkle the recommended amount on top of the soil and lightly mix in using a hand trowel.
Why are leaves flat and thin?
A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere. Leaves come in many shapes and sizes.
What is the purpose of a leaf on a plant?
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.
What is the advantage of a leaf being thin?
Their light weight also means that they can easily mimic water currents, allowing them to go with the flow without risk or damage. The thin leaves allow water to flow through and around the plants, minimizing damage.
Why is the leaf thin?
Leaves are thin, minimising the distance for carbon dioxide to travel into leaf cells. A midrib provides strength throughout the leaf, keeping it upright and sturdy in the wind. Chlorophyll is the green pigment that absorbs sunlight. Veins transport water and glucose around the plant.
At what time are stomata most likely to be open closed?
In general, stomata open by day and close at night. During the day, photosynthesis requires that the leaf mesophyll be exposed to the air to get CO2. At night, the stomata close to avoid losing water when photosynthesis is not occurring.
Why are there less stomata on the top of a leaf?
Explanation: Transpiration is the process of water evaporating at the surface of the leaf. Water exists the leaf through the stomata. In conclusion, a plant would want to have less stomata on the upper surface of a leaf to reduce the rate of transpiration.
What is the waxy layer that covers a leaf?
What protects leaves from getting too much water?
However, in plants that grow in very hot or very cold conditions, the epidermis may be several layers thick to protect against excessive water loss from transpiration. A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface.
What are the cells near the top of leaves called?
Palisade mesophyll layer – regularly shaped allowing many to pack together closely at the top of the leaf. These cells also have many chloroplasts in order to trap as much light as possible. Leaves are thin – ensures all cells receive light. Leaves have a large surface area.
How does a plant regulate water in its body?
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis .
What controls stomatal opening and closing?
Guard cell function Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
Where does the water enter the plant in photosynthesis?
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).
