BSC 1005 Unit 2 Plants and People Chapter 1 Introduction Why are plants green What is photosynthesis What is the process of photosynthesis What are characteristics of plants Who created classifications for organisms What is the order of the organism What is the biggest change to Linnaeus s classification classification What are the five kingdoms What does the length of the lines signify pg 4 What is the most important group in the green plant kingdom Contain chlorophyll to trap sunlight for photosynthesis Process by which plants gain carbon and energy for growth Get energy from sunlight to covert carbon dioxide from atmosphere into sugars and in return the sugars build all other compounds necessary for growth and provide energy Plants are green photosynthesis cell wall and reproduction through flowers fruits seed and spores Carl Linnaeus Kingdom phylum class order family genus species Now we classify based on evolutionary and genetic relatedness and plants Bacteria animals fungi protists The shorter the line the more closely related the organisms are Flowering plants angiosperms Chapter 2 The Special Features of Plant Cells Where did fossil fuels come from Characteristics of Fossil Fuels What is the cell surrounded What is the purpose of the cell by membrane membrane What lives inside of the cell Where is DNA located What happens in the cytoplasm because of organelles What do plant cells have that animal cells don t Where does photosynthesis occur What is the reverse chemical reaction of photosynthesis What is the carbon cycle What are the two systems plants use to get water What does the xylem system What does the phloem system do do Decay of plants and algae living in swamps and shallow seas Nonrenewable can only be used Finite eventually we may use them all up When burned adds carbon dioxide gas to atmosphere causing global once warming Cell membrane It controls the movement of substances in and out of the cell Cytoplasm and the nucleus In the nucleus Growth and metabolism Cell wall and chloroplasts Chloroplasts Respiration Carbon from atmosphere passes to plants then animals then back to atmosphere Xylem and phloem Transports water from the roots to the leaves Transports sugars from the leaves to all the parts of the plant that are not photosynthetic What is transpiration What happens during transpiration when the soil is dry What is the name of the special pores in the leaf surface What pair of cells surrounds Stomates and what do they do What happens in the cytoplasm What is the main component of cell walls What is cellulose What makes ethanol What is ethanol The movement of water from the roots to the leaves and then out of the atmosphere The plants wilt which leads to death Stomates Guard cells swell and shrink to open and close the pore Most of the cell s activities Cellulose on earth Most abundant organic compound Corn seeds containing starch that ferment to make ethanol Grain alcohol Chapter 3 How Plants are Put Together What part of the plant is above the ground What does the shoot consist What attaches the leaf to the What is the name of the patch of tissue at the top of the of stem shoot What happens at the shoot tip What connects the petiole with the stem at the base of the leaf What is the part of the leaf below ground What are they two different types of roots What is responsible for the growth in length of the shoot and the root Where do xylem and phloem form Where is xylem located Where is phloem located What is responsible for growth Shoot Stem branches and leaves Stalk called petiole Shoot tip New cells are formed and most growth takes place here Lateral bud dormant shoot tips Main root tap root and branch Root roots Tips The stem and root Toward the center of the stem Toward the outside of the stem Cell division in the body of the in width What is the significance in each ring of cells in a tree trunk What happens when a plant begins to make flowers What does hermaphroditic mean What contains the male reproductive cells and where do they form What contains the female reproductive cells What is the style What is the stigma What is inside the ovary What is the order of plant reproduction What are the two steps of plant reproduction What is pollination What is fertilization After fertilization what occurs in the ovule What does the plant embryo contain Why is the importance of the cotyledons What surrounds the embryo What protects the embryo How do ovaries become fruit stem and root Each ring is a year The shoot tips stop making leaves and make flowers instead The plant contains both male and female organs Pollen grains and in the anthers The pistol with ovaries at its base The neck of the pistol A patch of tissue at the end of the style Ovules which contains eggs Pollen is carried from the anther to the stigma to the pollen tube which goes into the ovary and then into the ovule The sperm then travels down the pollen tube and fuses with the egg cell Pollination and fertilization Transfer of pollen to the stigma Fusion of the sperm and egg Ovule grows and develops into a seed fruit Cotyledons root shoot access They store nutrients that help growth Endosperm The seed coat The ovary wall grows into a fruit Chapter 4 Pollination and Seed Dispersal What is an adaptation to bring the plant s male and female reproductive cells together What does self pollination lead to Why is genetic variability important What are advantages to wind pollinated plants What is the ear of a corn plant What is the silk coming out of the top of the corn plant What happens after pollen lands on a strand of silk Flowers Genetic uniformity Permits adaptation to a changing environment Lot of pollen do not need to attract pollinators therefore no petals and larger surface area of stigmas Collection of female flowers Bundle of stigmas styles It germinates and sends a pollen tube all the way down the silk to the ovule corn kernel What contains the anthers and releases the pollen What is the most common pollinator How do animal pollinated flowers attract pollinators What is the reward for the pollinators Characteristics of Bee pollinated flowers Characteristics of hummingbird pollinated flowers Characteristics of bat moth pollinated flowers Characteristics of fly pollinated flowers Characteristics of wasps pollinated flowers What are the two types of fruits Which type of fruit is adapted to be eaten by animals What are they different ways dry fruit can be dispersed The tassel male flowers
