Parts of plants Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow. Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air‚ water from the soil‚ and energy from the sunlight. During photosynthesis‚ the leaves use light energy to change carbon dioxide and water into food. (sugar) Flowers: These are the reproductive parts of

Roots The root system of a flowering plant begins its development from the hypocotyl of the embryo of the seed which gives rise to the primary root. Roots generally grow downwards into the soil (positively geotropic) and upwards (negatively geotropic). Roots do not bear leaves and therefore no nodes are present.Two kinds of root systems can be distinguished in flowering plants: tap root systems and adventitious root systems. Usually dicotyledons posses tap root systems and monocotyledons adventitious

Open Ended Investigation aim To photograph six different organisms (not including humans)‚ classify them to the level of ‘family’‚ determine one characteristic that places them in each of their groups‚ and then use those organisms to construct a dichotomous key. Method Collecting Photographs of Organisms 1. Walk to a location with natural flora and fauna. (In this case I went to the Jim Ring Reserve) 2. Photograph at least two different species of ducks‚ and if possible‚ other birds which reside

CHAPTER 36 PLANT CELLS The first barrier to form between daughter cells is the middle lamella. Daughter cells expand to their final size and make polysaccharides for a primary wall. After expansion stops waterproofing materials are added for a secondary wall. Water and dissolved materials move from cell to cell by way of pit pairs. A pit is a thin spot in the primary wall where the secondary wall is absent or separated from the primary wall by a space. Strands of cytoplasm called

the life cycle. A monocot seed with 2 genetic codes (2N) would grow by mitosis. The growth by mitosis would lead to the growth of the apical tips. The meristem cells (stem cells) keep dividing. Then the zone of elongation‚ the plant would get longer and grow. Eventually the cells would become specialized. The apical tips are at the top and bottom of the plant: causing it to grow roots and become taller. The plant eventually grows its roots‚ a stem‚ and 2 leaves. ****Woody dicot: the meristem cells
