Plant Unit Test Study Guide Biology 112 What are 5 characteristics an organism must have to be considered a Plant? 1. 2. 3. 4. 5. What 4 things do plants need to survive? 1. 2. 3. 4. A plant’s life cycle is 2 phases called the __________________________________________. The haploid phase is called the ___________________ generation and the chromosome number is ½. The diploid phase is called the _____________________ generation and it has a full chromosome set. The first plants on our planet evolved from an organism similar to today’s ________________ Botanists divide plants into the 4 groups based on 3 important factors: 1. Vascular tissue or no vascular tissue 2. Seeds or no seeds 3. Flowers or no flowers What are the names of the 4 groups of plants? 1. 2. 3. 4. Read the description carefully and select which GROUP of plant is being described: Moss and Relatives, Ferns and relatives, gymnosperms, angiosperms 1. 2. 3. 4. 5. 6. 7. 8. Bryophytes - __________________________ Seedless Vascular - ________________________ Evergreens - ______________________________ Divided into 2 classes (monocots and dicots) - _________________________________ Need water for reproduction - _________________________________________ Reproduce using spores - ______________________________________________ Seed vascular – __________________________________________________ Seeds are stored in cones - _________________________________________ 9. Seeds are often encased in fruit - __________________________________ 10. Leaves are called fronds - _________________________________________ 11. Often found in peat bogs and can be used as a fossil fuel - ______________________ 12. Flowering Plants - ______________________________ 13. Generally less than 20 cm - __________________________________________ 14. Largest # of plant species are in this group - _________________________________ 15. Liverworts and hornworts - ____________________________________ 16. Non-vascular – _____________________________________ 17. Most are now extinct - ____________________________________ 18. Shed their needles in 2-4 years - ________________________________ 19. Have rhizoids - ________________________________________ 20. Club moss/ground pine and horsetails - _____________________________ What are 4 functions of roots? 1. 2. 3. 4. What are the 2 types of roots? sketch: Explain the role of the “meristematic zone”: What advantage do root hairs give to the root system of a plant? The structure of a leaf is optimized for absorbing light and carrying out ____________________________ Equation for photosynthesis is: Carbon Dioxide + Water + Sunlight ________________ + oxygen What are the 3 functions of stems? 1. 2. 3. Explain the 2 factors that move water up through a plant: (Carnation activity) 1. 2. Label the following parts on your diagram: cuticle, epidermis, spongy mesophyll, palisade mesophyll, stoma, guard cells, vascular bundle, air spaces for gas exchange Can you label all the parts? This flower has both male and female parts so it is called a ________________________ What are the male parts of a flower? ______________________ Female parts? _______________________ What is the difference between a woody and herbaceous plant? What is the difference between an annual, biennial and a perennial plant? Fill in the table below by describing how the given characteristic will appear in both the monocot and dicot plant: Characteristic Stems (Vascular bundles) Monocot Dicot Petals Leaves Roots # of embryonic seed leaves Review all of your notes, guided readings, quizzes, assignments and labs GOOD LUCK!!
