Chapter 21 Plant evolution and adaptations Section 1- 1 Plant Evolution Plants are vital to our survival and provide oxygen for us to breathe and many of the foods that we eat. They make our lives comfortable by
providing products for clothing, furniture, and building materials. 2 Plant Evolution Modern day plants and algae share the following characteristics:
Cell walls made of cellulose Formation of a cell plate during cell division Use of chlorophyll during photosynthesis Similar ribosomal RNA Food stored as starch Same types of enzymes in vesicles.
3 Plant Evolution These shared characteristics between plants and algae suggest a common ancestor. 4 Plant Adaptations to Land Cuticle Fatty coating on the outside
of plant leaves that helps to protect the leaf from invading organisms and prevents unwanted water loss. STOMATA Openings in the outer layer of leaves that allows for the exchange of gases in plants with a cuticle. Vascular Tissues Specialized transport tissues that also provide support and structure. 5 Plant Adaptations to Land Reproductive Strategies
Some land plants reproduce through spores that have a waterproof protective covering Some land plants reproduce through the production of seeds. Some plants produce both (alternation of generations) 6 Plant Classification There are 12 plant divisions (same as phyla in other organisms). These 12 divisions can be placed into two groups:
Vascular Seed Producers Non-seed producers Club mosses, ferns, and horsetails Non-vasucular Mosses, hornworts, and liverworts 7 Plant Classification
Vascular plants contain specialized transport tissues that also provide support and structure. Non-vascular plants do not contain these specialized tissues, therefore, they seldom grow very tall. 8
