flowers on the plant
r u sure
Yes, I am sure. Flowers on the plant are the adaptation for reproduction in a berry plant. Flowers contain the reproductive organs needed for pollination and fertilization to occur, leading to the development of the berries.
How do tropisms help plants survive?(1 point) Responses Plants create their own food using chlorophyll. Plants create their own food using chlorophyll. Plants limit their needs in harsh conditions. Plants limit their needs in harsh conditions. Plants grow together with other plants. Plants grow together with other plants. Plants grow toward things they need.
Plants grow toward things they need.
Plants Unit Test 6 of 126 of 12 Items Question Use the scenario to answer the question. A student is studying the effects of sunlight on tomato plants. She chooses 6 tomato plants, making sure that each of them receives the same amount of water and fertilizer each day. She gives one plant 0 hours of sunlight each day, with the other 5 plants receiving 1, 3, 5, 7, and 9 hours of sunlight. At the end of the experiment, she has people try a tomato from each plant and has them rank the fruits by their sweetness. She also records the total number of leaves produced on each tomato plant. Which variable was controlled in the experiment? (1 point) Responses hours of sunlight hours of sunlight sweetness of fruit sweetness of fruit amount of water amount of water number of leaves number of leaves Skip to navigation
amount of water

The taiga biome has long, cold, dry winters and cool, wet summers. In three to four sentences, describe how the plants and animals would be impacted by a warm and dry summer and how they might survive. Support your answer with the abiotic factors in the biome.
During a warm and dry summer in the taiga biome, the plants would face challenges with water availability, as the already limited precipitation would be further reduced. This could lead to drought stress and impact plant growth and reproduction. Animals may struggle to find sufficient water sources and food, as plant productivity may be reduced. To survive, plants may adapt by conserving water through mechanisms like deep root systems or thicker cuticles, while animals may need to migrate to areas with more suitable conditions or adjust their foraging behavior to cope with the changing environment. The abiotic factors of the taiga biome, such as the long cold winters and cool wet summers, provide context for understanding the potential impacts of a warm and dry summer on the plants and animals within this biome.
