How is it possible for leaves to change color in autumn?
The trees leaves change color do to the waining of the sun. The less sunlight the less food the tree produces so it drops it's leaves so it doesn't wast energy keeping them healthy when the leaves can not photosinthisize the amount of food needed for this task.
Why do some plants lose their leaves and not evergreens?
They are way different species of trees. Some went one way and some the other. Evergreens evolved to have leaves year round, and others have evolved to make beautiful flowers and food. So they hibernate to make gain energy for spring. Evergreens dont make flowers or food.
A gardener accidentally trims the leaves of a green plant too short. The leaves are now much smaller. He notices that the plant grows more slowly than it used to. Which sentence best explains why the?
Trimming the leaves too short reduces the plant's ability to photosynthesize effectively, resulting in less energy production for growth. The smaller leaves also mean less surface area to absorb sunlight, water, and nutrients, leading to slower growth.
Why do trees lose leaves in winter?
There are different types of plant that survive in winter and that not like the one that doesn't survive are ANNUALs: these are the plants that produce a handsome amount of seeds during spring season. But they don't survive in winter. But in the spring season, new plants grow from the seeds.Second one is PERENNIALSThese are plants that survive during the winter season. Usually the plant part that breeds above the ground expires, but the roots are protected by snow layers.Then in the season of spring, this plant will start to grow once again.All plants find ways to survive the winter. The reason why plants lose their leaves are1- In the winter, heat becomes less available.2- In the winter, light become less available.3- In the winter, Water becomes less available.4- In the winter, minerals become less available.5- The plants then began to get rid of the leaves by discontinuing the flow of food to these expire leaves.And once the supply of the food from plant to leaves is close off, these leaves began to change their colour and with the passage of time they beginning to fall off.
How do swollen leaves help a plant to survive in warm conditions?
The swollen leaves are narrow so that less sunlight can be taken in for the plant because it already gets alot since its habitat is a warm enviroment so less sunlight would be ideal for it. So therefore less sunlight is taken in at the top of the leaves.
Why do plants with normal leaves grow more than plants with variegated leaves?
Because variegated ivy leaves have less chlorophyll, the plant produces less energy for growth. This means variegated ivy plants grow much slower than their all green cousins. Because they grow slower, they need much less food in the soil.
What is the main ways fishing kill animals?
It depletes their resources and leaves them with less food.
What are some characteristics of shade-tolerating plants?
Shade-tolerating plants typically have larger leaves to capture more light, lower growth rates due to less energy from photosynthesis, and adaptations to efficiently use available light, such as variegated leaves or vertical growth patterns. They are also often more tolerant of cooler temperatures and lower light levels compared to sun-loving species.
Why do trees lose their leaves in autumn?
trees make food during the summer from the sunlight they trap through the leaves and turn it into food, this is called photosynthesis but due to lack of sunlight during the winter, the trees store just the right amount of food to maintain the branches and the trunk but not the leaves so to save on food supply, the trees loose their leaves
Why conifers forest have needle shape leaf?
Even on mountains, the availability of water is less than on plains. To save water, the leaves are reduced to needle-like structures. Also, broad leaves can act as a surface for snow to accumulate. On trees like pines, the snow accumulates a little too but a not very much. This protects the plant from the cold snow or rain.
Why were animals launched into space?
Because through them we can accumulate information and they are less valuable than human lives.
Do the petals of a crocus and the leaves of a clover plant move for the same reason?
Yes. Because the leaflets become horizontal when making food but when it stops making food it closes together and looses less water. no need to thank me
What is the primary role of the needles of a scrub pine tree?
The "needles" on a pine tree or other conifer are the plant's leaves, where photosynthesis takes place. The needles are long and slender because of the environment of the trees. Needles lose less water and heat than typical leaves.
What are the advantages of letting the stems do the photosynthesising rather than the leaves?
Allowing stems to carry out photosynthesis can help supplement the overall food production for the plant. This can be beneficial in low-light conditions or when leaves are damaged. However, stems are usually less efficient at photosynthesis compared to leaves, which are specially adapted for this function.
Chlorosis is the phenomenon where leaves have what?
Chlorosis is the phenomenon where leaves have a deficiency in nitrogen. The leaves will turn yellow because they have less chlorophyll production.
Why are the leaves on the inside of a cabbage paler?
because they have less water
Why are holly leaves prickly?
Holly leaves are prickly as a defense mechanism to deter herbivores from eating them. The sharp edges and spiny points make the leaves less palatable and more difficult for animals to consume. This adaptation helps the plant conserve its energy and resources for growth and reproduction. Additionally, the prickly leaves can protect the plant during harsh winter months when food sources are scarce.
