correlation and causation: Many students do not understand the fundamental difference between correlation and causation. In this lab, stomata density variation likely results from interacting ...

On the east coast of Australia, in tropical North Queensland, lies the Daintree rainforest—a place where the density of trees ...

To avoid this, an individual plant may open its stomata and evaporate water which will lower the leaf temperature. Thus, one may hypothesize that leaves in the sun should have higher stomata density ...

On the lower half of the leaf are spongy mesophyll cells. These have air spaces between them to let gases flow. The stomata - tiny openings or pores – allow gases such as carbon dioxide and ...

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

To achieve this, the plant must allow CO 2 into the leaves, and allow oxygen and water (the waste products of photosynthesis) to escape. It does this through stomata. These are tiny holes in the leaf ...

He says they are preserved so perfectly that microscopic veins and stomata - the pores which allow leaves to take in air and release water during photosynthesis - are visible. The scientists ...
