Which of the following statements is true?
tissues are less complex than the organs they form.
organs must be made of the same type of tissue
a group of related cells working together is called an organ
organs are less complex than the cells they are made from.

Tissues are less complex than the organs they form.

Explanation:

Tissues are a group of cells that have the same structure and serve a specific function. Organs are more complex since they are made up of multiple tissues that are different in structure and perform different functions. For example tissues that form the lung include connective tissue, epithelial tissues and fibroblasts among others.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
