Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

Objective: To find out the food substance in food sample X‚Y and Z. Biological Principle: Test for lipids using the grease spot test Test for glucose using Clinistix paper Test for reducing sugars using Benedict’s test Test for starch using the iodine test Test for proteins using Albustix paper Test for vitamin C using DCPIP solution A control using distilled water instead of the sample should be included. Independent: different types of food samples Dependent: different types of food

Iodine is a test for starch while Benedict’s solution is a test for reducing sugars. When solution A is tested by benidicts test‚ the clear blue solution changed to a little reddish and brick red precipitate is formed.this result show that solution A is a reducing sugar. When carried out iodine test with solution A‚ the colourless solution remain unchanged . this tell us that starch is absent is solution A. When solution B is tested with Benedicts test‚ the clear blue solution remain unchanged‚ we

Introduction: Living‚ microscopic‚ unicellular organisms can be identified as microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of
