Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

An animal cell is not visible to the naked eye and is about 10 to 30 micrometers. A micrometer is one one-thousandth of a millimeter. They are so small that it takes a microscope with a magnification of at least 400x to be able to see inside the cell. These cells are what make up the basic units of structure and function in all living things. They carry out our life processes and make it possible for us to function and live. Inside these cells are organelles‚ which are smaller than the cell itself

board/combined science igcse.9998791839 india. Q.1 Explain transportation of water in plants. A.1 (1) Higher plants possess xylem which is associated with the transport of water. (2) Water absorbed by the root from the soil is transported to stem‚ branches‚ leaves and flowers. (3) The main structural components of the xylem responsible for the transport of water are tracheids and vessels. (4) As the root cells are directly in contact with soil‚they take up ions.due to this‚ a difference is created

CONCLUSION Angiosperms (flowering plant) include in phylum Anthophyta.Angiosperms are plant that have flowers and fruit. Their part of the flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon)‚ and pollen grains with a single groove while eudicots (true dicots) have two cotyledons‚ and pollen

Humans‚ animals and plants have a great relationship with each other‚ they need each other‚ and they make each other’s lives better. Without plants and animals‚ human won’t be able to survive or can not live till now because humans need plants and animals to feed themselves.

But human couldn’t take good care of animals‚ most of the animals in the
