All elements that are present in a plant need not be essential to its survival’.Comment.

Match the following:   Zinc   Calcium   Nitrogen   Phosphorous   Copper   1. Overall growth and chlorophyll structure. 2. Reproduction and root metabolism. 3. Root and flower growth. 4. Cell wall and overall strength. 5. Regulation of plant growth.

Plant stem cells such as those found in cambium tissues are able to -fight microbial invaders by becoming mobile and phagocytic. -produce nutrients for other cells. -remain undifferentiated but divide to produce cells that differentiate into new tissues. -exist as mature cells.

I’m having hard time understanding this could you please help?

Compare and contrast the acquisition and transport of water and nutrients in plants with the acquisition and transport of nutrients in humans. kind of in detail if possible.

. What characteristics of aquatic plants make them particularly problematic when they invade a body of water? Think about this in terms of the biological features of these organisms.

students are asked to pair a plant structure to its physiological function and give evidence for why that structure is important for the process they describe Anne The root hairs are used to pull in sugars available in the soil that give the plant energy for growth and reproduction Jamil : The phloem is needed for cellular respiration as transports the carbon dioxide the leaves in order to perform cellular respiration Shantal The cambium is important for photosynthesis because it allows water into the plant is needed as a reactant for photosynthesis Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant student correctly described a plant structure and its physiological function?

) Interactions between plants and other organisms can be complex and key to organisms continued survival. Joshua Tree National Park is home to the iconic Joshua tree plant, which is actually a very large species of yucca (Yucca brevifolia) with a tree-like appearance.  This is a long-lived species (hundreds of years).  There are many challenges to the continued survival of these plants.  Mature plants can store water allowing them to survive droughts, young plants have a smaller water storage capacity and thus will die off in dry times.  The only known pollinator of these plants is the yucca moth, which is becoming absent through most of the range of the yucca plant as the moth does not tolerate the increasingly warm climate in the region.  The warmer climate also decreases flowering (the plants need cold to induce flowering).  Adding to this challenge is the lack of natural seed dispersal of yucca.  It is though that historically the seeds of this yucca were dispersed by the now…
