अंग्रेज़ी में RHIZOID का क्या अर्थ होता है?
Rhizoid
Rhizoids सरल बाल की तरह protuberances है कि briophytes, Rhodophyta और pteridophytes की कम epidermal कोशिकाओं से विस्तार। वे संवहनी भूमि पौधों के मूल बालों के लिए संरचना और समारोह में समान हैं। इसी तरह की संरचनाओं शैवाल और कुछ कवक द्वारा बनाई गई हैं। Rhizoids एकल कोशिकाओं से बनते हैं, जबकि जड़ों कई कोशिकाओं से बना बहुकोशिकीय अंग है जो सामूहिक रूप से एक सामान्य कार्य को पूरा करते हैं। पौधे पानी में उत्पन्न हुए, जहां से वे धीरे-धीरे विकास के अपने लंबे पाठ्यक्रम के दौरान भूमि पर चले गए। पानी में या इसके पास, पौधों अपने आसपास के पानी को अवशोषित कर सकती हैं, किसी खास अवशोषित अंग या ऊतक की कोई जरूरत नहीं है। इसके अतिरिक्त, पौधों के विकास के प्राचीन राज्यों में, ऊतक भेदभाव और श्रम का विभाजन न्यूनतम था, इस प्रकार विशेष जल अवशोषित ऊतक की आवश्यकता जरूरी नहीं थी। एक बार भूमि पर उपनिवेशित पौधों के लिए, उन्हें कुशलतापूर्वक पानी को अवशोषित करने के लिए विशेष ऊतकों की आवश्यकता होती है, और खुद को भूमि पर लंगर डालना भी होता है। Rhizoids केशिका कार्रवाई से पानी को अवशोषित, जिसमें पानी rhizoids के धागे के बीच ऊपर जाता है और नहीं उनमें से प्रत्येक के माध्यम से जड़ों में करता है के रूप में

Mechanisms in Plant Development
In a process referred to as germination, the rhizoid pole grows to produce a
tubular rhizoid (Fig. 4.1). After the rhizoid emerges, the zygote divides
asymmetrically in the plane perpendicular to its longitudinal axis. This produces a
large apical ...

Intracellular labeling was stabilized in the presence of strontium ions, which have
