Given a scientific passage and an answer, generate a question for the given answer.

Passage: CHAPTER SUMMARY 30.1 The Plant Body A vascular plant consists of two organ systems: the shoot system and the root system. The shoot system includes the aboveground vegetative portions (stems and leaves) and reproductive parts (flowers and fruits). The root system supports the plant and is usually underground. A plant is composed of two main types of tissue: meristematic tissue and permanent tissue. Meristematic tissue consists of actively dividing cells found in root and shoot tips. As growth occurs, meristematic tissue differentiates into permanent tissue, which is categorized as either simple or complex. Simple tissues are made up of similar cell types; examples include dermal tissue and ground tissue. Dermal tissue provides the outer covering of the plant. Ground tissue is responsible for photosynthesis; it also supports vascular tissue and may store water and sugars. Complex tissues are made up of different cell types. Vascular tissue, for example, is made up of xylem and phloem cells. Answer: permanent tissue
A plant is composed of two main types of tissue: meristematic tissue and what other kind of tissue?

Passage: The atmosphere protects living things from the Sun's most harmful rays. Gases reflect or absorb the strongest rays of sunlight. Figure below models this role of the atmosphere. Answer: the atmosphere
What is the name of the protective layer of gases that surrounds the earth and blocks harmful rays from the sun?

Passage: connection is the basis of somatic reflexes. The corneal reflex is contraction of the orbicularis oculi muscle to blink the eyelid when something touches the surface of the eye. Stretch reflexes maintain a constant length of muscles by causing a contraction of a muscle to compensate for a stretch that can be sensed by a specialized receptor called a muscle spindle. Answer: somatic
Triggering a blink when something touches the surface of the eye, the corneal reflex is what type of reflex?
