How do plants make food when they have no leaves?
Plants, like cacti, don’t have leaves in the traditional sense. (Their spines are actually modified leaves.) But the cells in the body or “stem” of the cactus plant still contain chlorophyll. Thus, plants like cacti can absorb and convert energy from the sun through the process of photosynthesis.
How do trees make food in autumn?
Chlorophyll is important for plants to make food using sunlight. During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll. In autumn when it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules.
What happens to the trees that don’t have leaves?
The leaf is the part where the food is made out of co2,sunlight and water. Without the leaf the plant cannot prepare its food therefore not allowing it to grow and due to starvation it dies.
How do plants continue to live and get their food in the absence of leaves?
Answer: Plants can easily survive if there areno leaves for a few days. The food stored in the stems and roots acts as a supplement and help them to fulfill the food requirement when the leaves areabsent. For the gaseous exchange it makes use of lenticels of stem.
How does plants make their own food?
The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). The leaves of green plants contain chlorophyll, which absorbs sunlight for producing food. This food is then used by the plant itself as well as other animals, including humans.
How do trees produce food?
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
How do trees make leaves?
In general, during growth cells divide, cells elongate, and cells differentiate into structures such as roots and shoots. Meristems can also produce new meristems called primordia. For example, an apical meristem in a bud produces new meristems called leaf primordial. Each leaf primordium will grow into a new leaf.
Why did no leaf remain on the trees?
No leaf remained on the trees because of the hailstorm that passed. 2. Lencho was very sad and disappointed because of the loss of his crops. Lencho was very sad because of his destruction of his crops.
How plants make their own food?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
